The four escaped from the centre early on Sunday

The Sri Lankan men in their 20s and 30s disappeared from the Haslar Immigration Detention Centre in Gosport, early on Sunday.

The men, who were in civilian clothing, escaped after scaling a perimeter fence at the centre.

Hampshire Police say the men were all being held while waiting to appeal against deportation but are not considered dangerous.

Earlier this year several inmates at the centre started a brief hunger strike in protest at being kept in what they claimed were bad conditions.
