Above the message, the author wrote the abbreviation of 'quote of the day' - a nod to the atrocities which saw 48 injured after three men launched a crazed knife attack at Borough Market last night.

Londoners have rallied round to help victims and the emergency services in a continued display of acts of kindness.

This morning staff from Sainsburys were handing out sandwiches and bottles of water to police officers while a vicar was seen giving much-needed cups of tea to exhausted emergency workers.

Online the hashtag #PrayForLondon has seen hundreds offer up their homes and office space to help those left stranded.

And in a moment of true darkness for the country, some have tried to find some light. In one image showing people running for their lives, a gentleman wearing devil horns caught the eye of people on social media.

Despite being caught up in the chaos, he had somehow managed to not spill a drop of his drink. In the image, he held the half-drunk pint glass with caution as he joined the throng of people fleeing from the scene of the atrocity.

Kind women offer stranger who was caught up in terror their spare room A young man caught up in the London Bridge incident has thanked two strangers who offered him a bed for the night after being left stranded. George Moss, 22, was unable to get home after police put a cordon between Borough Market and Elephant and Castle. Mr Moss, originally from Guernsey, also lost his phone during the evening, which meant he initially had no way of contacting family or friends to ask for a bed to stay. After borrowing a phone from a reporter at the scene, Mr Moss was able to get in touch with Holly Robinson and Mary Lynch, who tweeted that strangers with nowhere else to stay could crash at their home in Vauxhall. A police officer stands guard on Borough High Street. One witness said she saw three people with what appeared to be their throats cut on London Bridge amid the 'utter chaos' Speaking from his new, temporary accommodation, Mr Moss said: 'I was out this evening trying to make my own way home at around 11.30pm but couldn't make my way through anywhere. 'I met (a reporter) who lent me his phone so I tried to get hold of my mum and dad. 'After that I went towards Vauxhall and found Holly and Mary who very kindly gave me a place to stay. (Without them) I would have been in a pickle, I wouldn't have anywhere else to go. 'Having someone so close and so willing to help makes a massive difference.' Ms Lynch, 23, from Nottingham, said: 'I think we saw when things (terror attacks) had happened in Orlando and Manchester and thinking if I had been in that situation I would want to know that people were going to open up their homes.' Ms Robinson, from Birmingham, said her original tweet was able to reach many followers after it was retweeted by former Newsround presenter Lizo Mzimba, who she once met after asking him for a selfie. She said: 'I just tweeted it (the offer) because we were here, we have friends stuck in various places. You have to give whatever you can, whenever you can. 'That's all we wanted to do, we didn't know if anyone would come but it was just to put the offer out there.'

Terrifying footage from the scene shows police officers shouting 'Clear the scene now!' as panicked pedestrians flee. London Ambulance said multiple resources were attending the area.

The car that the three men were in is believed to have veered in an 'S shape' across the bridge and has driven towards the Shard and is south of the river. There are unconfirmed reports that it is a B&Q and Hertz van.

The bridge is in lock down and the area around it is closed with bus routes being diverted, as armed police and a bomb squad attend the scene and boats search the water.

The attacks in the streets of London come just days after armed troops were pulled off the streets of Britain.

Thousands of soldiers were deployed by Theresa May following the bombing at Manchester arena as she raised the UK threat level from 'severe' to 'critical'.
