More than 12 police officers a week are being attacked monitoring Britain's transport networks, figures show.
There were 1,939 reported assaults against British Transport Police (BTP) officers in the three years to October 2018, resulting in more than 230 injuries, Freedom of Information requests have shown.
Leeds station in West Yorkshire had the greatest number of assaults, with 66 incidents between 2015 and 2018.
London Victoria came second, with 60, closely followed by Manchester Piccadilly with 56 attacks in the last three years, the force said.
Glasgow Central station saw the most assaults of any station outside England with 38.
Overall, assaults on BTP officers were recorded at more than 500 locations, including level crossings, hospitals and in custody, with 226 incidents of actual bodily harm, and a further 13 more serious grievous bodily harm offences.
One BTP officer who was attacked on duty told the Press Association he quickly returned to work because his absence cut his team's manpower by a third.
Nigel Goodband, chairman of the British Transport Police Federation, said:
British Transport Police called the figures a "shocking revelation".
