INDIANAPOLIS (AP) — Authorities say as many as three suspects are being sought in alleged vandalism at the Congressional Medal of Honor Memorial in Indianapolis.

The Capitol Police Section of the Indiana State Police says in a statement that the public’s help is being sought in identifying the suspect or suspects.

Police say maintenance workers at the memorial on Monday noticed damage to a descriptive pillar and investigators determined that a young male apparently pried open the pillar around 10:50 p.m. Saturday. They say two other males gathered with him. Damage was estimated at about $300.

Surveillance images were posted online by police. Anyone with information is asked to contact investigators.
