Eithan Teanby was on a weekend release from a Lincolnshire jail and there are fears because he is currently on medication. Det Insp John Symes said Mr Teanby's family were worried, and added: "We are growing concerned. My understanding is that Mr Teanby is currently taking prescription medication and we have concerns that he may not have access to his required dosage."
