The man, aged between 25 and 35, tapped on a window in his victims home, in Sapley, at about 9.20pm on October 10. The woman, in her 20s, opened the curtains to see the man expose himself. Officers are linking this offence with another at 10pm on September 29 in Constable Road, St Ives, when the man ran up behind two women in their 50s and exposed himself. The victims walked off and told him to go away but he exposed himself twice before walking away. Officers believe the man may also have committed 10 similar offences in the St Ives area between March 2010 and August 2011. He is described as white, about 5ft 7in, medium build with a local accent. He has a round face and distinctive large eyes. PC James Howard said: This man normally targets victims near open areas and public walkways, between 8pm and 10pm, and wears a dark woolly jumper and a dark beanie hat. I am keen to trace this man as soon as possible so anyone who recognises the image should not hesitate to get in touch. INFORMATION: Anyone with information should contact PC Howard on 101 or Crimestoppers, anonymously, on 0800 555111.
