Motorway roadblock for police training
Motorists caught up in M55 traffic have been told a road block this morning was down to police training.
The operation, which saw four police cars swoop on a vehicle at about 9.30am, closed a lane on the motorway between Preston and Kirkham.
Motorists reported seeing arrests being made.
But force officials said the action was a training exercise.
The motorway is currently flowing freely.
