Police are searching for a man who was seen acting inappropriately towards three women in Lincoln.
The first incident was reported to police on Thursday, March 20 at around 1.25pm.
A woman reported being followed by a man on a pushbike on the riverbank near the bridge at the end of Russell Street.
He allegedly cycled past her a number of times with his hand down his trousers and was moving his hand up and down as if masturbating, before cycling off towards The Plough pub.
A second incident was also reported on Thursday, March 20 just before 1.30pm.
A woman had entered Boultham Park through the Rookery Lane entrance opposite Blackbourn Road with her young daughter and puppy.
She walked towards a wooded area in the direction of the riverbank and was followed by a man on a pushbike. He cycled past her four or five times with his hand down his trousers as in the earlier incident, police said.
In both incidents the man is described as wearing chef-style checked trousers, either blue or black checks, with a black jacket.
He is though to be in his 20s, and is described as between 5ft 9in and 5ft 11in, of average build, with short light brown/blonde hair.
He was riding a pale green coloured mountain bike.
A third incident was reported around 1.30pm on Monday, March 24 in the area of Russell Street.
A woman reported seeing a male urinating on the river footpath near to the bridge at the end of Russell Street.
He is described as wearing a green Adidas hooded top with red stripes, around 5ft 9in, and riding a pale green coloured bike which had a fishing rod attached.
Anyone with any information concerning the incidents or who may have seen a man matching that description or behaving suspiciously, is asked to contact Lincolnshire Police on 101 quoting incidents 208 or 209 of March 2o or incident number 307 of March 24.
