A man was arrested on Tuesday for illegally entering the ASML building in Wilton.

Police say Clifton Allison faces charges for entering the facility on Danbury Road.

Allison entered the building two different times on Christmas Day.

Police say he left multiple bags behind during his first entry.

The building was evacuated until the bomb squad could clear the area, but no explosives were found.

Police say Allison was questioned and denied being in the building.

He was caught and arrested for returning later in the day after being questioned.
