THE presence of forensic police officers at Woodvale Secondary College raised questions among parents and students as they arrived at the school this morning.
Concerns of serious matters arose, but Police Media spokesman Sam Dinnison said officers were simply investigating an overnight break-in.
He explained an alarm was activated at the Woodvale Drive premises about 3.30am.
He said they knew someone was in one of the buildings, but nothing was stolen.
