A ‘devil worshipper’ who killed his cousin has escaped custody while being treated at hospital.

Mosa Abid, 22, from Northolt, has fled custody on October 10 at 11:40am while receiving out-patient treatment at Homerton Hospital, Hackney.

Abid stabbed his 18-year-old cousin at a house in Buddings Circle, Wembley, on October 15, 2017 after previously writing a letter to Satan pledging to kill his cousin Moamen Settar.

After the stabbing, an ITV report tells that the two younger sisters of Mr Settar found their brother on the floor with four or five stab wounds to the chest following hearing screaming from the room.

The next morning, police found him at a bench in Northolt, concealing a knife in his sleeve. Further police investigation at his house in Dehavilland Close, Northolt, found several devil worshipping documents in his room.

Abid pleaded guilty to the manslaughter of his cousin on the grounds of diminished responsibility and was sentenced to an indefinite hospital order in June 2017

After escaping the hospital, Metropolitan Police have shared descriptions of him claiming he is tall and thin, wearing damaged spectacles on both sides and wearing a dark suit with a black Puffa style hooded jacket.

Members of the public are advised not to approach Abid.

Officers are urging anyone who may have seen him to call 999 quoting CAD 2866/Oct10.
