POLICE have issued a safety warning to young girls following two sex pest offences which were reported within half an hour of each other.
Officers believe the incidents in Ellesmere Port might be linked.
Although none of the teenagers were touched or injured, officers have now issued safety advice to females walking home at night.
The first incident happened between 10.30 and 11pm on Friday, as two 15-year-old girls were walking past the entrance to the new Asda store in McGarva Way.
PC Frank Morris, of Ellesmere Port police, said: 'The offender stopped his vehicle by the side of the girls and asked if they wanted sex.
'The girls told him to go away and the man made an obscene suggestion. He then exposed himself and the girls ran off.'
The man is described as white, aged about 40, with a local accent, short dark receding hair, of slim build, scruffy appearance, brown eyes and clean shaven.
He wore a dark blue tracksuit top or a jumper and his car was possibly a dark blue Citroen.
PC Morris said the second incident happened at 11.01pm when a 16-year-old girl was stopped by a motorist in Pooltown Road.
He said: 'The driver asked the girl if she wanted sex. She refused and he drove off fast down Pooltown Road.
'The girl says he might have passed her a couple of times beforehand in Stanney Lane.'
The driver was described as possibly half-caste, with dark hair, a foreign accent and in his early 30s. The car could have been a dark green Mondeo.
Cheshire police advise women going home at night to get a taxi or, if walking, buy a personal attack alarm from a DIY store, walk in well-lit areas, don't take short-cuts down alleys and don't take lifts from strangers.
