Police have issued a fresh appeal following a disturbance at a train station in Glasgow earlier this year.
The incident happened at Queens Park railway station at around 4pm on Saturday, July 11.
Officers believe the man captured on CCTV will be able to help with the investigation.
Sergeant Gray, of Greater Glasgow Violence Reduction Unit, said: “We are continuing our investigation into this incident, which would have been frightening for those members of the public who were at the train station.
“We are eager to talk to the man in these images as we believe he may have information that could assist us.
“We would urge anyone who may recognise him, or who has any information, to get in touch as soon as possible.”
