Chilling words of the sniper.

THIS is the chilling letter written by the Washington sniper, demanding $10 million to stop his killing spree.

The handwritten note, which is three pages long, was left behind after a man was critically wounded in a Virginia car park on October 10.

Titled 'Call Me God', the author says he had tried to contact the police but they had not listened to him. He also warns them to 'prepare their body bags' if his demands are not met.

Sniper suspects John Allen Muhammad, 41, and his companion John Lee Malvo, 17, were arrested on Thursday as they slept in their car at a highway rest stop.

As the handwritten letter was released last night, US police were linking the murder of a woman earlier this year to the case, bringing the toll to 11 dead and three wounded.

Keenya Cook, 21, was shot deadon February 16 when she opened the door of her Tacoma home. Police believe there are links with the Washington murders as Muhammad was in the area at the time and knew her family. Former soldier Muhammad has so far been charged with six counts of first-degree murder.

Investigators said a rifle found in the men's car has been linked to 11 of the shootings.
