Indecent behaviour at Vic bowling alley

A man in his 40s or 50s allegedly masturbated in front of a 15-year-old boy in the toilets of a Melbourne bowling alley last week.

The indecent assault unfolded at the venue on Latrobe Street in the city about 12.50pm on Friday, November 1, with the adult fleeing shortly after.

Victoria Police say the man has a solid build and grey hair and they have released an image of a man they believe can help with their enquiries.
