Police investigating the murder of a schoolboy in north Belfast last year are carrying out searches in the area for the second time this week.
Thomas Devlin was murdered as he walked home from a sweet shop
Thomas Devlin, 15, died after being stabbed five times as he and two friends walked along Somerton Road on 10 August.
The searches are taking place at empty flats in the Mount Vernon district.
On Tuesday, police searched the same area and took away several items for scientific examination.
In September, the PSNI confirmed the prime suspects in the inquiry were two young men with a black and white dog.
Thomas, a student at Belfast Royal Academy, was a talented musician who played the horn at school.
He had just bought sweets from a nearby shop and was on his way home when he was stabbed.
His 18-year-old friend was injured in the attack, but not seriously. A 16-year-old boy managed to escape.
A number of people detained for questioning about the murder were subsequently released without charge.
