Detective Superintendent Richard Tompkins said: "We have officers who are actively looking for Johnny however, he has now been missing for almost 24 hours, and with no confirmed sightings, we are becoming increasingly concerned.
"Johnny is serving a hospital order for convictions relating to arson and serious assault, which is why it is very important that the public do not approach him under any circumstances but should call 999 immediately.
"We are investigating three separate incidents of arson to bags of rubbish, which occurred overnight, in areas within a couple of miles of the hospital grounds which may be linked to Johnny.
"Arson has potentially fatal consequences and we therefore ask the public to be extra vigilant within their local communities.
"If you see anyone acting suspiciously near property or deliberately starting fires to items such as bins, please call us immediately on 999."
