Drug dealer Darryl Jervier seventh to flee HMP Sudbury
A convicted drug dealer is the seventh inmate to go on the run from an open prison in Derbyshire in the past month.
Darryl Jervier, 26, who was serving four years for conspiracy to supply Class A drugs, disappeared from HMP Sudbury on Friday.
Derbyshire Police has warned the public not to approach him.
Last month, six prisoners, including inmates serving time for violent crimes, went on the run from the Category D men's prison.
One man has been missing for more than 20 years after being allowed out in 1992.
In the most recent high-profile case, Michael Wheatley, known as "Skullcracker", carried out a raid on a building society in May while on the run from HMP Standford Hill in Kent.
Jervier is described as black, 5ft 11in tall, of medium build, with brown eyes, shaved black hair and speaks with a London accent.
Police said he had connections in Hertfordshire, Middlesex and London.
Anyone with information is asked to contact Derbyshire Police.
