Three immigration offenders are still on the run after breaking out of a detention centre.

The security breach came as the Home Office launched a new bid to toughen up its enforcement of immigration laws.

The men escaped from the Campsfield House centre, near Kidlington, Oxfordshire, along with four others who were later recaptured.

One was caught cycling away from the scene and a second man injured an ankle leaping over the perimeter fence.

Another escapee was later found seven miles away at the Oxford University Botanic Garden, although staff denied reports the fugitive had helped himself to their tomato crop.

The escape overshadowed the Government's launch of a strategy to deal with immigration offenders, including plans on detention and deportation.
