The 27-year-old singer started kicking the doors and hitting the walls Sunday after a male nurse suggested he participate in more therapy sessions, a source told the Mirror.
The clinic assigned him a personal security guard after his weekend outburst, spin.com reported.
Doherty had been back with model-girlfriend Moss Aug. 6 at the Rhythm Festival in Bedfordshire, England. In an Aug. 17 BBC interview, Doherty referred to Moss as his "missus," People reported.
But that same night, he was back in jail, facing drug charges. A judge ordered the singer to reside at the Priory clinic from 10 p.m. to 8 a.m. daily.
Moss, who lost modeling jobs after tabloid photos appeared showed her snorting cocaine, is back on top of her career, People reported.
"A certain kind of model has that inexorable attraction to a certain type of bad boy. It seems Kate is one of those girls." said Michael Gross, author of "Model: The Ugly Business of Beautiful Women."
