A series of controlled explosions were carried by the British Army on a suspicious car in Dunmurray just outside Belfast last night.
A police spokesman said that the alert ended with nothing being found.
In a separate incident there were reports of clashes between rival groups of nationalists and loyalists in the Whitewell Road of north Belfast last night.
