Two 15-year-old boys have been arrested after up to 30 wraps of drugs were seized by police.
At about 10.15am on Tuesday 7 August 2012, police were called to the McDonald's restaurant at the Rock in Bury.
Officers were alerted by local authority-run CCTV operators based in Mill Gate who saw the two 15-year-old boys acting suspiciously and subsequently called the police to investigate.
When officers from the Bury East Neighbourhood team attended, they carried out a drugs search and found about 30 wraps of drugs on the two teenagers. The drugs have been sent off for forensic recovery, but it is believed they are some form of Class A drugs, possibly heroin.
The two teenagers have been bailed pending further inquiries.
A large amount of cash and three mobile phones were also seized.
Inspector Charlotte Cadden said: "It is extremely saddening to see such young men caught red-handed with so many drugs. We still need time to conduct a thorough investigation into exactly what these drugs are and where they came from, but the mere fact two young teenagers were found in possession of what we believe may be heroin is quite shocking.
"What this incident does demonstrate is how good our relationship is with the local authority who look after the Mill Gate shopping centre. It was CCTV operators who saw these two boys exchanging quick glances and looking like they may be up to no good, so they responded quickly and called police.
"Officers from the Bury East Neighbourhood team attended within minutes and as a result of that swift and decisive action we were able to seize the drugs and arrest the two teenagers.
"Drugs are a blight on our community and whether you are 15 or 50, dealing drugs is a very serious offence. We will continue to work closely with all our partner agencies and when we receive intelligence of possible drug dealing, we will take action."
Anyone with information about drugs should call police on 101 or the independent charity Crimestoppers, anonymously, on 0800 555 111.
