An off-duty policeman was seriously injured and another three were slightly hurt when they arrested a knife-wielding man in Paceville early yesterday morning.
The incident happened on St Rita Steps at about 5.20am when a man threw a glass at a group of people. When one of the officers identified himself, the man spat at him and produced a knife.
He ran off when the policemen tried to arrest him but was apprehended after a struggle.
The police said that one of the officers sustained a knife wound to his side, another to his hand and another was punched in the face.
