Police have released new details on London's most wanted sex attacker - the 'Nightstalker'.

The man, who preys on elderly women, is believed to be behind more than 100 sex attacks and burglaries in and around south London over the past 18 years.

New clues

Cops are building up a profile of the pervert from victim reports. They believe the man is religious, possibly a catholic as he stole rosary beads from one terrified elderly lady.

A recent victim described markings on the right side of the 'Nightstalkers' face, which may have been caused by a rash.

Detectives hunting the man think he travels by motorbike which he parks nearby and wears biker-style clothing.

Operation Minstead

Operation Minstead is the latest concerted effort to snare the sex beast. In Norwood and Downham he is believed to have sexually assaulted two people in the past eight weeks. There is a £40,000 reward.

DNA profile

Cops have the man's DNA yet have been unable to match it to anyone in their database. Forensics shown he is a light skinned black man, 35-45 and from the Windward Islands in the Caribbean. He has a connection to Brighton and his mother died in 2000.

Police added the suspect could be living, visiting or working in Honor Oak or Forest Hill area.

Latest attacks

He is also thought to have broken into three homes in Lee, Downham and Norwood. It was one of these victims who helped police compile the e-fit. Det Supt Simon Morgan said:

"The victim saw the suspect in dark conditions but states he is a light skinned black man, with markings on the side of his face. These could be a number of things such as freckles, scarring or spots."
