Police are probing reports of a serial flasher seen driving around rural areas before jumping out of his car completely naked.
Officers today warned women to be on their guard following a number of reports in the Garstang and Over Wyre areas on Wednesday night.
The offender is a white male, aged between 40 to 60 and driving a dark green, three-door Peugeot, thought to be a 206 model.
Officers have said it is possible the vehicle’s registration plate has been tampered with.
The man has not approached any of the five victims, all female aged between 30 and 50, but has been seen touching himself.
DI Andy Bunn said: “We would advise women to be extra vigilant. We need to find this individual so we can assess any risk he may pose.”
The first sighting of the man was on Castle Lane, Garstang, at 4.45pm. The same man was later seen on Longmoor Lane, Nateby, at 7pm, Ainspool Lane, Churchtown, at 7.30pm and on Brock Road, Great Eccleston, at 7.45pm.
The last reported sighting was at 8pm on Thistleton Lane, Thistleton.
Despite a police search of the area that night the man was not found.
Police have stressed that while the man made no attempt to approach or assault the women they are still concerned about the behaviour.
Anyone who may have seen the vehicle or man is urged to contact Police on 101, quoting log LC-20130530-0573.
