A GROUP of five people ripped wood from a bridge and threw it into the water in Droitwich, causing it to become unsafe and unable to use.
The criminal damage happened last Thursday near Stoulton Croft.
The four young men and one young woman – aged around 16 – were all wearing dark clothing and fled before police arrived.
Witnesses or anyone with information on their identities should call police on 101 or Crimestoppers on 0800 555 111.
