Lincolnshire Police are very keen to trace a man who was allegedly the victim of a robbery and / or an assault but never came forward to report his experience.
At just after 4am on March 16, a report of a robbery at St Peters Hill in Grantham was received by police.
Two men, Ramanus Mastiatis, 24, and Mantas Saulyrtis, 22, were arrested and later charged.
Police have identified and spoken to two alleged victims, but it is believed that there may be a third victim - a man dressed in a grey jacket.
Despite an appeal at the time, this man has not yet come forward, and police are urging him or anyone who knows who it might be to call 101.
