Humberside Police is appealing for witnesses following three reports of a man exposing himself to young girls in Bridlington.
Three incidents have been reported this week, all by girls between the ages of 12 and 14.
The first was alleged to have taken place on New Pasture Lane Bridge at 4.10pm on Monday, the second at 3.40pm on Tuesday near Westgate Park, Main Road, and the third happened near Bowling Green Park at 3.45 pm also on Tuesday.
None of the girls were approached by the man or hurt in anyway.
