Police in Spalding have arrested a man on suspicion of possession of a firearm.
They were called to the town centre at around 9.30 this morning (May 13th) to reports of a man with what looked like a gun in his pocket.
The A151 Winsover Road was closed for a time between the St Thomas Road and Swan Street junctions to both vehicles and pedestrians but has now re-opened.
Officers say they cannot as yet confirm what type of weapon was involved, or if it is a replica. There are no reports of threats having been made or injuries.
