POLICE believe a man who threw a stone inside a mosque was part of a gang which later attacked a teenage boy.

The first incident was on Monday at 7.30pm when a white man went into a mosque at North Road in Ravensthorpe and threw a stone before escaping in a silver Vauxhall Vectra.

No-one was hurt.

Police say the next day at 7pm a gang of white men drove up to a 15- year-old boy and threw a substance at him at High Street, Heckmondwike.

Insp Martin Lister said: "Nuisance behaviour like this will not be tolerated."

Anyone with information should phone police on 01924 431059.
