Vasile Caceban was reported as disappeared by staff at Park Royal Center for Mental Health in Acton Lane, just before 10.30 in the morning of April 16.
The officers have released images that show Vasile in the morning that went to where you can see with a top with purple camouflage, gray tracksuit funds and light -colored trainers.
Around 4.20 pm, the 36 -year -old was seen in CCTV in a store in Kilburn High Road with a gray tracksuit top and a red shirt, which wore the black backpack he had bought before.
Police consultations suggest that since then has bought a large black backpack and new clothes.
The police describe it as white, 5 feet 4 inches high or average construction with brown hair.
Although the officers believe that it is likely to be in northwestern London, particularly Brent, the investigations suggest that, since it disappeared, he has traveled to Hyde Park in Westminster and back, probably using the train network.
The Superintendent of Detectives Andrew Brien, of the Northwest Command Unit, said: “An investigation of a high -risk missing person was rapidly launched when we knew the risk raised by Vasile.
“It is important that we return to the installation where it is being treated.
“Extensive patrols have been carried out in the area where it is believed to be, but now we are appealing the public’s help.
“It is possible that Vasile sleeps rude or campe in the Kilburn or nearby area.
“Check the sheds or gardens and keep your eyes wide open if you walk through parks and open spaces.
“Your information could be key to helping us find Vasile and keep the public safe.”
Anyone who sees Vasile is urged not to approach him, but to call 999 in his place, providing reference 01/7385436/25.
Any person with other information should call the non -emergency number of the police at 101.
