BLACK cab rapist John Worboys has struck up a grim friendship with Baby P’s killer after they both got jobs on their prison hospital wing.

Worboys, 61, and Steven Barker, 42, have grown close after attending meetings in the chapel and singing in the choir.

They both work on the healthcare unit at HMP Wakefield, West Yorks, cleaning and preparing and serving food.

A source said: “They are really close and spend a lot of time together.”

Worboys was convicted in 2009 of 19 offences against 12 women.

Barker was caged for “causing or allowing the death of a child” in 2007 after Peter Connelly, 17 months, died from horrific injuries.
