Police closed a bridge over the M4 in Swindon this afternoon during a welfare incident.
It’s believed officers were responding to reports of a male on the road bridge above the motorway between Liddington and Chieseldon at around 5.30pm.
A young man, thought to be in his 20s, was taken into the care of the ambulance service after reportedly being detained by the police for his own safety. 
It’s understood he has since been taken to a place of safety.
