Wife killer Malcolm Webster is under special protection after getting a beating in jail.
The former Takapuna resident was battered in the head and body by an enraged fellow con armed with a metal pole.
Webster, 52, is serving 30 years for killing his first wife for $400,000 in life insurance and trying to kill his second wife in an identical staged car crash.
The Sun newspaper reported a source at Shotts jail in Lanarkshire said Webster was a "marked man" and was attacked in an engineering shed.
"He has a black eye and a bad head wound," he said.
