A knifeman who ran amok at a London train station, stabbing at least one victim, shouted 'kill all Muslims' during his rampage, witnesses have said.

A man was injured during the attack at Forest Hill station in south-east London this afternoon and is currently being treated in hospital.

Witnesses said the man was waving his arm around in the air and shouting 'Death to Muslims' as he 'marched up and down' outside the station after the attack.

Miguel Oliveira, 36, said he came 'face-to-face' with the attacker, who was 'shouting uncontrollably' after he allegedly stabbed a man.

Mr Oliveira, a composer, said he was met with a 'wave of people' when he arrived at the station shortly after 1pm following the incident.

He said: 'The first few were shouting 'he's got a knife, he's got a knife' and then all of a sudden the next ones said 'Oh he's been stabbed, call the police'.'

He added that some members of the crowd were shouting: 'He wants to kill Muslims'.

Mr Oliveira left the station but returned a few minutes later amid confusion over the whereabouts of the attacker.

He said: 'I doubled back and I went back to the station and actually came face-to-face with him.

'He had just come out - not the way they were saying. He was walking towards me and he was shouting stuff like 'Death to Muslims' and 'Go back to Syria'.'

Eyewitness Richard Etienne was on the train to Forest Hill when he was confronted by the attacker.

The videographer, from Forest Hill, said: 'I was on the third carriage and the man with the knife was walking from the fifth carriage at the back.

'I don't know when he got on, but I realised he was marching down the carriages as the train left Honor Oak Park, which is the stop before Forest Hill.'

In the two or three minute interval between the two stations, the attacker terrorised the train.

Mr Etienne said: 'He was black, wearing a dark Barbour jacket and dark jeans.

'He looked about 5' 7' or 5' 8' and he was marching down the train kind of muttering loudly to himself, so everyone could hear: "I'm going to kill me a Muslim", that's what I kept hearing him say.

Police were called to Forest Hill station shortly after 1pm today following reports of a stabbing

Witnesses told about the knife attack on Facebook this afternoon

'The majority of people were trying to ignore him and some were starting to move away towards the back of the train.

'Then he stopped where I was sitting and turned to face me.

'His facial expression was like a man on a mission, full of anger and rage.

'He then turned away from me to look at a woman with a hijab sitting opposite me. She looked in her twenties.

'I could see the back of him and that's when I saw the knife in his right hand.

'The blade looked about five to six inches and it looked like a kitchen knife with a black handle.

'He was holding it at hip level but his hands were stiff and the blade was pointing towards her, so he was holding it to her.

'I think I heard a woman next to her, say: "Oh God, he's got a knife."

Witnesses said the man was shouting 'Death to Muslims' during the station rampage

After a tense few seconds the attacker said: 'I don't want me a Muslim woman, I want me a Muslim man.'

He then stormed off towards the first carriage.

At this point several passengers began setting off alarms on the train and hurrying towards the back carriage.

Mr Etienne said: 'I set off an alarm.

'It was like everything was in slow motion, I didn't feel frightened at the time.'

Then as the train pulled into Forrest Hill station, the attacker launched his assault.

Mr Etienne said: 'I heard a woman scream from the first carriage, then I saw three or four guys leap towards where the scream came from.

'People were running from the first carriage, so I couldn't see the guy who got stabbed.

'The only thing I saw was a woman in a hijab standing outside the train wailing, with blood on her hands.

'I saw the guy run from the train up to the other side of the platform, but then a parked train obscured the view.

'The police came around six or seven minutes later.'

Commenting on how passengers reacted he said: 'It was really London-like, everyone seemed to be looking out for each other, keeping calm and looking to check the children were ok.

'Nobody wanted to antagonise him before the attack happened.'

Police said this afternoon that they are not treating the incident as terror-related

Shellby Curry, 24, was with her one-year old child when she saw a man 'waving what looked to be a knife in his hand' near the station and screaming words like 'Muslims f****** hate them, kill them all'.

She described the attacker as a black man with short hair, who she thought appeared to be in his late 30s or early 40s.

Olusegun Adegbiyi, 53, who works in a taxi office by the station described seeing more than a dozen people flee from a man who came out of the station.

Olusegun said: 'I just saw about seven or ten people running from the station, it looked like they were running for their lives.

'They were looking back, as if running from someone.

'Then this guy came out, he was slim, black and looked about 35 or maybe he was more like mixed race.

'He was wearing jeans and a jacket and kept shouting 'You shouldn't be scared of Muslims'.

'I didn't see a knife, he had one gloved hand and looked like he was carrying his other glove in the other hand.

'They were all running from him, then another group of about ten people came out and they all started running away from the same guy.

'I saw the guy go back into the station, running and then I didn't see him again.'

Emergency services were called to the scene at the suburban station in south of the capital

Another local businessman who saw the victim being taken out of the station said: 'He was properly stabbed up.

'His face was cut on one side, that was a great big cut and then he had two other cuts on his body.

'One was on his armpit I think.

'He looked like he was Muslim in terms of his skin colour, but he was brought out naked so I wouldn't have known if he was wearing robes.

'He looked in his thirties, he was a young guy.

'I saw a whole load of police vehicles and about three ambulances.'

A station employee, who didn't wish to be named, said: 'The guy who was stabbed was Muslim and it happened on a train.

'We're not allowed to say anything, but I think it was a hate crime.'

Several people phoned the police, who arrived around ten minutes later and restrained the man, Miss Curry said.

'I was walking along and someone stopped and said 'be careful, he's got a knife'. As I looked around there he was.

'I just grabbed my baby and ran across the road. Looking back [I saw] him marching up and down waving his arm about.'

Witness Richard Etienne tweeted: 'Those in the Forest Hill area stay alert. I've just seen a man brandishing a knife claiming he will 'kill all Muslims'. Police alerted.'

Another witness added: 'A massacre in Forest Hill station a man shouting 'who is Muslim? I want to kill a Muslim?' stabs several times a Muslim passenger, no reason.'

A British Transport Police spokesman said: 'We are currently at Forest Hill railway station, after being called to a serious assault at 1.18pm.

'One person has been arrested following the incident and is currently in police custody.

'One man was treated by ambulance staff at the scene and is currently en route to hospital.
