Parsons Green attack suspect named as 21-year-old Yahyah Farroukh. CCTV footage published showing man carrying bag which resembles bomb. The Syrian refugee was reportedly arrested outside a fast food restaurant in west London on Saturday night. UK terror threat level has been reduced from critical, its highest level, to severe.

One of the suspects behind the Parsons Green tube bomb attack has been named by British media.

Multiple news outlets, including Sky News and The Daily Mail, have identified the terror suspect as 21-year-old Syrian refugee Yahyah Farroukh.

Police have yet to confirm his identity. A video, obtained by The Sun newspaper, and republished below by MailOnline, purports to show Farroukh being arrested after working a shift at a chicken shop.

The video was recorded outiside Aladdins in Hounslow, southwest London, just before midnight on Saturday.

A man who identified himself over the phone as the store's manager confirmed to Business Insider that Farroukh is an employee there.

A Facebook page for Farroukh, reviewed by Business Insider, says that he is from Damascus, the Syrian capital, but moved to the UK and entrolled at West Thames College in Hounslow, where he learned English. The page also listed a record label and a nightclub as previous employers.

The same day Farroukh was arrested, police raided an address in Sunbury-on-Thames, Surrey. According to the local council leader, who spoke to the Press Association, Farroukh was brought up at the property by foster parents.

ITV News published CCTV footage recorded on the same street showing a man leaving the foster parents' home around an hour and a half before the bomb attack.

The man was carrying a Lidl shopping bag which resembles the bomb which went off on a District Line train a few hours later.

An 18-year-old was also arrested on Saturday in connection with Friday's attack. According to the Daily Mail, Farroukh and the 18-year-old were raised in the same home, by the same couple.

The home belongs to Ronald and Penelope Jones, who have fostered hundreds of children in the area and were honoured with an MBE award by the Queen in 2010.

Information on Farroukh emerged as the UK government reduced the official terror threat level from critical, meaning an attack is expected imminently, to severe, suggesting an attack is highly likely.

Home Secretary Amber Rudd said the police had made "good progress" with their investigation, enabling her to decrease the threat level.
