Police handling of the disappearance of Richard Okorogheye are to be investigated by a watchdog following complaints by his mother.
His mother, Evidence Joel, contacted police the following day, but he was not officially recorded as missing until 8am on March 24.
Mr Okorogheye’s body was found in Epping Forest Essex on April 5.
His mother later said she had been “disappointed” with the initial police response to his disappearance.
On Monday, watchdog the Independent Office for Police Conduct (IOPC) said it will investigate Ms Joel’s complaints about the way she was initially treated by police, and how her reports about her son’s disappearance were handled.
It will also look at the Met Police overall handling of the missing person report.
IOPC regional director Sal Naseem said: “Our thoughts are with Richard’s family and friends and all those affected by this tragic loss. We have spoken to his family and explained our role.
“Our investigation will establish whether the police responded appropriately to the concerns raised that Richard was missing.
“We will examine whether the force appropriately risk assessed those reports, and if the amount of resources the Metropolitan Police dedicated to its enquiries were suitable based on the information known by the police and the risks posed.
“As there is a mandatory requirement for police forces to refer to us incidents which result in a death or serious injury, we will examine the actions and decisions of the police when dealing with the missing person report made in respect of a vulnerable young man.
“We will also consider whether Richard’s or his mother’s ethnicity played a part in the way the initial reports of his disappearance were handled.”
Mr Okorogheye left his family home at around 8.30pm on March 22 and headed in the direction of Ladbroke Grove.
Police said further inquiries have established that he then took a taxi journey from the W2 area of London to a residential street in Loughton, Essex.
He was last seen on CCTV in Loughton, walking alone on Smarts Lane towards Epping Forest at 12.39am on March 23.
