Police are appealing for information to help find moped riders who attacked police cars during a Remembrance Day parade.
Two patrol vehicles were damaged while officers along with members of the community were taking part in a Remembrance parade that was being held at Brookvale Park in Erdington on 12 November.
While the officers were away, West Midlands Police said the suspects "took the opportunity" to smash the windows of the cars.
Shortly after, two men were spotted driving off towards Brookvale village on a moped.
Police are now appealing for information and are examining CCTV in order to catch whoever was responsible for the "cowardly" attack.
Chief Superintendent Kenny Bell from Birmingham East Police said: "It is absolutely disgusting how these individuals took advantage of a time when my officers were marching shoulder to shoulder with members of the community during Remembrance parades.
"I would urge anyone with information to get in touch so that we can bring those who committed this cowardly crime to justice."
Officers are particularly keen to hear from anyone who witnessed two people acting suspiciously on a moped in the area.
Anyone with information is asked to contact Birmingham Police on 101 quoting crime reference number 20BE/243780A/17.
