Police in Skelmersdale said they were attacked by a "large" group of teenagers.
Officers patrolling Sandy Lane said they had missiles "launched" at them and their vehicles on Tuesday night. According to a post on the Skelmersdale police Facebook page, the police have been providing an increased police presence around Skelmersdale due to an increase in anti-social behaviour.
In recent months police have been called to "multiple" incidents of anti-social behaviour and in September a Section 34 Dispersal Order was put in place after officers at the Concourse Shopping Centre had projectiles thrown at their car causing damage to their vehicles.
