Police have issued a warning after a "devil-worshipping" killer has escaped while on escorted leaving from a secure hospital.
Mosa Jamal Abid, 26, was on escorted leave in a newsagent in West London when he ran off at about 3pm on Monday.
Metropolitan Police have issued another appeal as he is still missing nearly five days later, warning "he can be violent" and should not be approached if seen.
Abid, then 22, stabbed his cousin Moamen Setta to death in 2016. The “self-confessed devil worshipper” wrote a rambling letter to Satan before carrying out the attack.
Abid also absconded in October 2019 from Homerton Hospital in Hackney, east London, the force added.
On this occasion Abid is believed to have fled eastbound along Uxbridge Road in Ealing before possibly entering Brent Lodge Park.
In a statement released via the Met Police, Abid’s family appealed directly to him, saying: “Mosa – if you are reading this then please do the right thing and return to hospital so you can get the care and support you need.
“Every day that goes by and we don’t know you are safe and well is heartbreaking to us.”
Officers searched the area but Abid could not be found.
CCTV enquiries are ongoing and searches of the local area continue.
Abid was last seen wearing a navy hooded jacket with black trousers and blue trainers.
The force said he requires medication for an ongoing health condition and might attend a hospital for help or approach local mosques during the Iftar period for food and drink.
Detective Inspector Alistair Stillgoe, from the local policing team in west London, said: “I understand that the longer Mosa remains missing, the more concern will grow amongst the public.
“I want to reassure people that we are utilising all our available resources, including deploying specialist officers, to help to locate him.
“We have had calls from members of the public and these have been followed up; some of these sightings have centred on the Hanwell area.
“Mosa may be sleeping rough in the area so I would ask people to keep an eye out and if they see someone fitting Mosa’s description, not to approach him, but to call us immediately.”
Police have urged anyone with information to call 999, quoting CAD 3873/10Apr.
