Two teenagers arrested in connection with a raid at a mobile phone store in Edgware have failed to meet their bail deadline.
A gang of youths snatched 23 mobile phones as well as a Notebook laptop from Carphone Warehouse in Station Road in January.
Two 15-year-old boys were later arrested for theft and were bailed to return to a North London police station.
The pair were due to return yesterday but failed to turn up. Barnet police are investigating.
