PSNI are investigating two alleged hate crimes in Belfast.
The incidents happened at around 10pm on Saturday in the north of the city.
A 15-year-old boy was assaulted while making his way home along the Oldpark Road, close to the junction with Rosapenna Street.
Police said that two men on bikes approached him, directed sectarian comments towards him and attacked him with metal bars. The victim was taken to hospital.
Around 15 minutes later another 15-year-old male and his friend were approached by two males on bikes on the Crumlin Road , close to Russell's shop.
