Police investigating an attack on an autistic teenager in Lisburn will revisit the scene where he was beaten on Thursday.

Scott Vineer, 17, was repeatedly kicked in the head during the attack at a disused furniture showroom near the Lagan Towpath.

The teenager went missing on 6 September and was found unconscious a day later.

He remains in a critical condition in hospital.

The police will speak to motorists and pedestrians in the hope of finding out more about what happened.

His mother had raised the alarm at 22:00 BST on Thursday after he failed to return home from college.

He was found by a police dog handler on Friday evening.

Scott is a student at the South Eastern Regional College in Lisburn where he also attends a job club, run by the learning disability charity, Mencap.

No motive has yet been established for the attack on the 6 ft 3 in (1.9m) teenager, who has been described as a “gentle giant”.

Detectives are not aware if anything was stolen from him, and they say there is nothing to suggest a sectarian motive.

Police described it as a “brutal and senseless attack on a vulnerable young man”.

A 17-year-old man, arrested in connection with the assault, has been released on police bail pending further enquiries.

Anyone with information is asked to contact the PSNI.
