Maui police arrested a 16-year-old boy in connection with four Maui county buses that were shot at in December.

Damage to the buses occurred three separate times in mid-to-late December as the buses were traveling on their designated routes, according to a police department news release. Police said two of the buses were damaged on the Wailuku Loop route.

Last week, police asked for the public’s help to find the culprit or culprits involved in shooting bus windows with a pellet gun. Bus personnel discovered cracked windows and projectile holes after the buses had returned to its headquarters.

Police said the four buses sustained damage on the driver’s side.

There were no reports of any injuries.

Police arrested the 16-year-old boy Wednesday on suspicion of four counts of first-degree criminal property damage, four counts of second-degree reckless endangering and four counts of obstructing government operations.

He was released pending investigation.
