A man and woman are being questioned by the PSNI about the sectarian murder of a Catholic schoolboy in Belfast last year.
The pair, both aged 22, were detained by detectives in Belfast hunting the killers of Thomas Devlin.
Thomas, 15, was stabbed to death in the north of the city after going out to buy sweets with friends last August.
He was stabbed five times in the back during the attack as he walked home along the Somerton Road.
While several people have been questioned about the Belfast Royal Academy student's murder, no-one has been charged.
Detectives have said the prime suspects in the inquiry were two young men seen with a black and white dog.
As the probe continued, a Police Service of Northern Ireland spokeswoman confirmed: "A 22-year-old man and a 22-year-old woman were arrested in Belfast this morning in connection with the investigation into the murder of Thomas Devlin ."
