TRANSPORT police probing two violent incidents on a train to Gourock have today issued pictures of two men they want to trace.

Officers have released stills, taken from CCTV footage, of individuals they believe may be able to assist with their enquiries.

It follows a pair of incidents on a service from Glasgow Central to Gourock on December 22.

They occurred shortly after 11.30pm on board the train while it was travelling between Paisley Gilmour Street and Gourock.

As a result of these incidents a man was injured and required hospital treatment.

The man in the first image is believed to have boarded the train at Glasgow Central and to have left it at Langbank.
