She said the attack was racially motivated and described it as a hate crime.She went on: “I think this was probably confidence by numbers. It started off with this smaller group of people who were joined by between 20 to 30 and they just viciously attacked these individuals because they were asylum seekers.”She said: “The victim had come from a friend’s house and the three individuals were waiting for a bus when the unprovoked attack occurred.”They were viciously attacked because they were asylum seekers.”Once they identified who these people were they attacked them in the most appalling way.”A total of 16 people had been arrested by Monday evening and the police had put out an appeal to identify others. Seven have been charged and seven remain in custody.Det Supt Corrigan said: “I genuinely don’t think people have gone out that night with the intention to commit this horrific attack.”You’ve got a really difficult mix of youth, the time of night, alcohol, and it only takes one person to say something that could spark off something massive – which is what I think has happened on this evening.”This is a random attack and the suspect and victims aren’t known to each other that we are aware of.” They were viciously attacked because they were asylum seekers. Once they identified who these people were, they attacked them in the most appalling way.Det Supt Jane Corrigan Police on Monday charged seven people, including two brothers and a brother and sister, over the attack, while others remain under arrest. Reker, an Iranian Kurd who has lived and studied in area for several months, has been scarred for life with severe injuries to his face, detectives said.Theresa May said the assault was “absolutely despicable”.Speaking at the start of a three-day trip to the Middle East, she echoed the comments of local Tory MP Gavin Barwell, who branded the attackers “cowardly and despicable scum”. Scotland Yard detectives have released CCTV pictures of others they are hoping to identify in connection with the Friday night assault.Det Supt Jane Corrigan, leading the investigation, said the attack was “an unprovoked attack as a result of him being an asylum seeker”. Mrs May said: “This was an absolutely abominable attack, completely unacceptable.”I absolutely agree with the sentiments of Gavin Barwell when he commented on this and I just hope that anybody who has any information about this will give that information to the police.”It is alleged the boy and his friends, Dilshad Mohammed, an Iraqi Kurd, and Hamo Mustafa, were first attacked at the stop near the Goat Pub in Croydon. Reker was then chased 100 yards into a housing estate, and severely beaten around the head and face until unconscious.
