Head of the Manchester police Superintendent Wayne Cameron says the victim of the motorcycle robbery in which a police officer was killed, has been getting death threats.

Superintendent Cameron says the police have put measures in place to protect the man, who remains hospitalised.

The man was shot and wounded last Friday October 27, after armed men stole his motorcycle.

38-year-old Melvin Smith, who was assigned to the Manchester Community Safety and Security Branch, was shot dead by an armed robber, while attempting to foil the robbery.

Meantime, Superintendent Cameron says the 3 men taken into custody in relation to the killing of corporal smith are still being interviewed.

One of the suspects will face identification parade shortly.

Superintendent Cameron says the police are continuing to gather information to assist in their investigation.
