Wednesday, 3 February 2010 (BBC) -- A man who throws animal semen on schoolgirls is being hunted by police following a sixth attack.
Detectives in Greater Manchester, described the assaults, all in the Bury area, as "disgusting".
The man follows young girls before they discover they have been smeared with the liquid.
Police have released a CCTV image of a man they want to speak to. The first attack was reported in November and the latest was last week.
Det Insp Lynne Vernon, from Greater Manchester Police, said: "We have six separate incidents and do not know the motivation behind them - while we do not want people to be frightened unnecessarily, we are taking these reports seriously.
"None of the victims was physically harmed in anyway but this is still a disgusting act and the person responsible must be caught.
"I'd ask people to take a good look at this image and if you know anything about this man, please contact us.
"He is not necessarily connected to all of the incidents but we would like to speak to him as part of our inquiries."
The first victim, a 14-year-old girl, was followed by a man on Kennedy Drive in Unsworth, on 13 November.
He asked her the time and was standing uncomfortably close to her.
When she got home, she noticed a sticky liquid on her tights.
The substance was analysed by police and later identified as animal semen.
A 15-year-old girl was smeared with liquid by a man on 7 December on Ostrich Lane, Prestwich.
Later that day another 15-year-old was followed.
On 17 December a 14-year-old girl was in a shop on Mill Gate in Bury town centre with her mother when a man bumped into her and wiped a white substance on her bottom.
The next day, a man followed two 13-year-old girls on Bury Old Road, near to the M60 in Prestwich.
In the latest attack, on 25 January, a man approached two girls, aged 15 and 16, on Pinfold Lane, Whitefield, and asked them the time.
One of the girls then noticed liquid dripping from her skirt.
In each incident, the offender was described as being a white man, aged between 25 and 35 and was carrying a bag.
