THE brave wife of a man who was punched in a "racist" London Underground attack has told how she chased the thug off, swearing in Spanish.

Spanish-speaking Kilian Ahmed, 35, screamed "Cabrón! Hijo de Puta!" - meaning 'son of a b****' - as the brute ran off down the platform at Upton Park station.

The furious wife has described the vile attacker - who allegedly launched a torrent of abuse at the couple before hitting her husband - as "just rude".

Shocking footage emerged of the man punching Kilian's husband Jubair, 31, in the face before bolting off the train at the east London station.

In the disturbing clip Kilian and Jubair are sat minding their own business when the apparently unprovoked attack is launched.

A passenger began filming the incident shortly before Jubair was assaulted, and British Transport Police confirmed a 33-year-old man has been arrested.

Jubair told the Evening Standard: "When we boarded and sat down he was shouting and swearing, I didn’t look at him because I knew maybe it was dangerous.

"He come over to us as we approached East Ham station and started swearing at me. He was shouting in front of me.

“At the next stop it looked like he intended to get off but when the train arrived suddenly he hit my cheek and ran away. My wife followed him shouting to everyone to help to catch him."

Jubair says he was left shocked and dizzy after the vicious attack - and is struggling to eat in the wake of it as his jaw is bruised.

Kilian told Bangladeshi TV network Channel S: "I talked to this man, I say, ‘Why you touch my husband?’ This man tell me, ‘Shut up, shut up, please, shut up’.

“I say, ‘I not shut up, why you touch my husband? Why?’ It’s rude, because why touch my husband.”

Shockingly Jubair says it is the second time he has been the victim of an alleged hate crime since moving to the UK.

He also claims attacks have worsened in recent months, saying: "I see cases like this and I think its increased. I don’t know why this man talked to me, for what reason."

Jubair says he wants justice and for his attacker to be punished.

A British Transport Police spokesman said a 33-year-old man had been arrested on suspicion of assault occasioning actual bodily harm and using threatening and abusive words and behaviour. He has been bailed until November 14.

As the train pulls to a halt, the violent attacker swings a seemingly unprovoked punch at the man's face.

The victim's head thuds loudly against the train's window behind after the brute lands the forceful blow.

Reeling from the attack, the victim clutches his face while his companion jumps up and chases the attacker off the train.She can be heard screaming "call a copper" as she pursues the thug down the platform.

The attack is thought to have been racially aggravated.

Another passenger filmed the footage - but there is no clear indication of what happened before the recording.

It also remains unclear why the bystander was filming the couple.

Miqdaad Versi, Assistant Secretary General of the Muslim Council of Britain, posted the footage on his Twitter page.

He wrote: "Apparent racist attack on London Underground @BTP: Hope perpetrator is found & faces justice for this despicable unprovoked attack."

British Transport Police said they are probing the incident and are unable to make any further comments at the moment.

They added anyone with information can contact them on 0800405040 quoting reference 554 and today's date.
