ARMED police have arrested a man at gunpoint in an operation between Scottish and English forces.
Six officers with automatic weapons surrounded a taxi on the A80 in Cumbernauld yesterday morning.
The scene unfolded close to where three men were killed in a car crash on Wednesday.
Witnesses say a man who appeared to be of Asian origin was standing with his hands on the vehicle, a silver Citroen Berlingo operated by local cab firm Central Cars.
He was being questioned by police, who had stopped the taxi by blocking its path with one of their vehicles.
Police refused to confirm or deny whether the operation was linked to any anti-terror investigation.
