An inmate at North Sea Camp open prison jumped into Boston’s Maud Foster Drain to evade police on Friday.
The man, in his 60s, had allegedly stolen from the Morrisons store in Boston Shopping Park and fled to Horncastle Road before jumping into the water opposite the Maud Foster Windmill.
Lincolnshire Fire and Rescue was alerted to the incident at 11.24am and sent two swift water rescue boat teams from Boston and Spalding which recovered the man from the water.
He was then taken to Pilgrim Hospital for a check up before being collected by prison staff.
A Lincolnshire Police spokesman said: “Morrisons did not want to pursue a complaint so there was no further police action.”
The news comes after national spotlight fell on North Sea Camp and other open prisons when Conservative MP Philip Davies raised concerns about absconders - including rapists and murderers - walking out of open prisons.
The Daily Mail highlighted the case of Ivan Leach, a sex offender and dangerous robber, who walked out of the Freiston Shore last year.
Speaking about the issue, MP Mark Simmonds said: “I have written to the Home Secretary about the North Sea Camp and have also held discussions with the prison authority to ensure that prisoners in North Sea Camp are thoroughly vetted and pose no threat to the public.”
