It has emerged that a man who escaped from police custody at Altnagelvin Hospital was one of three men arrested in the North this week in connection to a spate of burglaries around Glenties and Dungloe.
The PSNI says the man does not pose a risk to the public.
The 40-year-old who escaped was one of three men arrested in Derry on suspicion of involvement in burglaries and other criminal acts in Co Donegal.
He had been taken to the hospital on yesterday afternoon after saying he was unwell.
The police say the man remains at large.
The arrests followed burglaries and break-ins in the Glenties and Dungloe areas. We understand a number of the items which had been stolen earlier have been recovered.
Gardai say the Text Alert scheme was an important element in getting that information gathered, and are urging people to participate in and use that scheme.
Gardai are now trying to trace the movements of an 05 registered grey Astra car which they believe is connected to the Glenties incidents. However, they are rejecting reports that a pensioner was robbed.
Meanwhile, as part of their investigations into what's been described as a well planned break-in at a shop and filling station in Leitirmacaward on Saturday night, gardai are trying to trace the movements of a dark coloured Insignia car with a Northern Ireland regisration.
Gardai have also renewed an appeal to businesses to be vigilant and review their security procedures.
