Vredosian

The Vredosians were a species of near-humans with grey skin, triangular teeth and quills instead of hair.

A Vredosian had been captured by Torchwood Three, but she escaped and took a job at the Washington Hotel. She was later indirectly found because of her infestation of bedbugs, which caused an abnormal increase in bug-bites at the hotel. Owen Harper took her into custody, but he let her go to deal with a bus crash. (TWN: Pack Animals)
