A man has been arrested by detectives investigating the murder of north Belfast schoolboy Thomas Devlin.

The 15-year-old was stabbed in the back five times as he and two friends walked home along the Somerton Road on 10 August after buying sweets.
Detectives staged a reconstruction of his final movements on Wednesday night, just hours after his funeral.
Last weekend, three people arrested in connection with the murder were released without charge.
Thomas' 18-year-old friend was injured in the attack, but not seriously. A 16-year-old boy managed to escape.
Thomas, a student at Belfast Royal Academy, was a talented musician who played the horn at school.
