Four held after hoax bomb alerts at Belfast school

Police in the North have arrested three teenage boys and a 22-year-old man after a series of hoax security alerts close to a west Belfast school.

St Colm's in the Twinbrook area has been the target of seven hoax alerts since September, disrupting classes.

Several controlled explosions were carried out during the latest alert on Wednesday.

There have been claims that republicans may have targeted the school because it allowed a visit by British Royal Marines earlier this month.
