RSPCA inspectors had to deal with a slippery customer when an uninvited guest arrived at a Thurrock freight firm.
"The staff weren't sure if the snake was dangerous or not but our staff at RSPCA Brighton Reptile Rescue, which is now looking after the 1ft-long snake, believe he's an Indian cat-eyed snake, or boiga, which is mildly venomous," said a spokesperson for the animal charity.
