Police are growing increasingly concerned for the welfare of a Cambridge who has been missing for nearly four days.
Harry Ogg, 21, went missing on Thursday (October 11) after visiting his parents in Mitcham.
Mr Ogg, a pianist who graduated from Cambridge in June, is believed to have arrived at Wimbledon station at 9.20pm on Thursday evening (October 11) using his Oyster, but police have confirmed he was last seen in Tooting.
The music student has not gone missing before and is known to have a history of depression.
He is described as white, 5ft 9ins, of medium build with dark hair and was last seen wearing a navy blue duffel coat and blue jeans.
He is known to have links with the Kilburn area as well as Mitcham.
A facebook site to help find him has already attracted more than 15,000 members with his brother Tom Ogg, urging people to help in the search by keeping an eye out in London parks including Wimbledon Common which he said was of "particular interest."
