BRITISH Transport Police are appealing for help from three men.
Officers investigating an affray on board a train from Reading to Newbury last year.
Last week, they released three images in connection with the fight, which happened on Saturday, November 20.
At around 9.10pm, a group of males began fighting in a carriage.
Officers believe the men in the CCTV images may have information which could help their investigation.
