Four young men were arrested overnight after they were found tagging buildings on the Northwest Side.
Two juveniles and two 18-year-olds were caught tagging four buildings and a water tower on Menchaca Street.
When police arrived at the scene, the boys had taken off but were found a short time later by a police helicopter in the 1200 block of West Laurel.
The four boys will be facing felony charges.
Police say the damages could be around $11,000.
