A 30 year old man has been arrested in Derry on suspicion of aggravated vehicle taking, dangerous driving and a number of other motoring offences.
It follows the theft of a delivery van from Abercorn Road in the City this morning.
Shortly after 7 o'clock, it was reported that a delivery driver was making a delivery to a filling station on Abercorn Road when two unknown males entered the vehicle and drove off in it.
Police observed the vehicle on Letterkenny Road and signalled for it to stop but it failed to do so colliding with the police vehicle in the process.
The vehicle was abandoned a short time later on Quarry Street and the two males made off on foot. The suspect was detained a short distance away and remains in custody this evening.
The PSNI is urging anyone who witnessed the incident, or anyone who saw the men leave the van on Quarry Street, to contact them at Strand Road on 101, or by calling the independent charity Crimestoppers.
