Police were called to Bolton Road shortly after 9am on Sunday (May 24) due to reports of a man climbing onto the roof of a property and refusing to come down.
The man, 42, then began “throwing objects from the roof and setting small fires” and causing “substantial damage” to houses and cars before he sustained an injury due to falling debris.
Some properties were evacuated before the man, from Adlington, was arrested nearly seven hours after the incident began.
The suspect was arrested on suspicion of assault, assault on an emergency worker, arson with intent to endanger life and criminal damage and remains in custody.
