Two teenagers arrested on suspicion of murdering a celebrity minder as he confronted a gang of moped thieves have been bailed.
Ricky Hayden, 27, died of stab wounds inflicted in the attack outside his home in Chadwell Heath, east London.
The Havering Council employee had also worked in security at ITV and acted as a bodyguard for high-profile celebrities including footballer Peter Crouch and model Abbey Clancy.
His father, Paul Hayden, 54, a security guard at ITV, was also injured in the incident.
The victims had confronted a gang of up to four men attempting to steal a moped after hearing a disturbance outside their home in the early hours of Wednesday morning, Scotland Yard said.
Detectives bailed a 19-year-old man until a date later this month and a 16-year-old boy until a date in mid-October.
