Police have found a man who they said was potentially violent and was last seen at Toronto East General hospital's psychiatric ward.

Police began looking for Mitchell Oraa, 30, Tuesday at 6 p.m. ET. He was last seen at the hospital about six hours earlier. 

Oraa was picked up by ambulance on Wednesday and taken to Toronto Western Hospital.

Once staff checked his identity and realized who he was, police were called at about 7:45 p.m. He remains at the hospital.

There was no immediate word on his condition or the exact area where he was picked up.

When Oraa was still missing, Toronto police Const. Wendy Drummond said he was "known to be violent" and was also considered to be a danger to himself.

Police had advised people not to approach him, and said they should call 911 immediately if they saw him.

Second psychiatric patient

This is the second time this year that police have gone searching for a psychiatric patient who was left the hospital unexpectedly and residents in the surrounding area say they have security concerns.

Earlier this year, Michael Eligon, 29, walked out of the same hospital on the morning of February 3.

Police went searching for Eligon after calls came in about a man in a hospital gown who was holding scissors.

Eligon was subsequently shot dead by police on Milverton Boulevard.

John Riley lives on that street and Eligon approached him in his driveway before he was shot.

He said he couldn't believe that another patient had escaped.

"I just feel it is bad security on behalf of the hospital," Riley said during the search. "I’m quite alarmed."
