A woman was left puzzled after a mystery caller knocked on her door in the early hours of the morning and left behind a four-foot long snake on her doorstep.

The homeowner said that a young woman knocked on her door in Cricklewood, north London, in the early hours of Thursday morning. When she answered the door, the woman asked for ‘Andrew’ before walking off, leaving a pillow case on the doorstep.

Confused, the homeowner spotted that the pillow case appeared to be moving. Looking inside, she discovered that it contained a four-foot-long South American boa.

At that point, she quite sensibly decided to call the police.

A spokeswoman for the Metropolitan Police said that the snake, which officers have nicknamed Kojak, is ‘friendly’, is in good condition, and appeared to have been handled before.

Officers kept the snake in an office at Colindale police station for several hours before it was taken to London Zoo.

The spokeswoman added: ‘If you are the owner of the boa and wish to be re-united with your pet, or have information about where he has come from please call police on 0300 123 1212.’
