Cops smashed a suspected drugs ring after a woman was allegedly spotted with a stash - in her bra.

Four people were nabbed in co-ordinated dawn swoops that saw cannabis, diazepam, suboxone and blue pills, seized during the operation in Glasgow's Castlemilk.

The Evening Times joined dozens of officers as they battered down doors of four flats in the same street yesterday.

We can exclusively reveal details of the operation, which was the result of months of intelligence gathering from local residents.

Cops in helmets and body armour fitted a hydraulic device to the door frame, while another member of the squad crashed through the front door with the rammit.

After shouts of "police, don't move", the search teams raced into the properties and their investigation got underway.

Sniffer dogs were also drafted in to help search the four properties, which are directly across the road from each other.

Glasgow Times:

Inspector Mark Nicol, from the Community Improvement Partnerships (CIPs), lead yesterday's operation.

He told the Evening Times: "This operation was about showing the local community that we will act on their information.

"If you tell us about drugs, we will do something about it.

"It also sends the message to those people engaged in criminality - it won't be tolerated."

The two men and two women - aged between 31 and 40 - were detained in connection with alleged drugs offences and reported to the procurator fiscal.

After a 7.30am briefing at Police Scotland's Jackton Training Centre, officers split into four teams and were driven in a convoy to Raithburn Road.

Detectives had spent weeks compiling intelligence about individuals suspected of selling potentially lethal heroin.

Glasgow Times:

Information passed to officers included a woman who allegedly had a stash of drugs in her bra.

Chief Inspector Graham McInarlin, area commander for Linn, Langside, Pollokshields and Southside Central, issued a stark warning to those committing drugs crimes.

He said: "We will to continue to target those who trade in misery and operations like this reinforce the message that we will not tolerate crime.

"We understand there's no one else for the public to turn to with their concerns and that's why it's important we work together with our partners to take action.

"And a benefit of the national force, is that we can use national resources, including the dogs unit.

"I know it takes a lot of courage to report something to police, but people need to know they can come to us in confidence."

As part of the CIPs, officers work closely with partner agencies, including housing associations.

Staff from Glasgow Housing Association, the police and the fire service set up CIPs to tackle anti-social behaviour, vandalism, violence and disorder.

Local beat officers and cops from the nationwide Violence Reduction Unit teamed up for yesterday's operation.

Police carry out drug raids early in the morning to avoid the chance of alerting suspects and prevent them disposing of drugs.

Search teams found a lone male asleep on the floor of one property and once he had been woken up, an extensive search of the flat got underway.

Officers were also posted around the perimeter of the block of flats.

The day of action came after around 40 separate tip-offs on suspected drug crime in the area.

Officers were told that people were visiting the flats around the clock, causing noise and disorder.

Search teams also focussed on a silver car which was parked in the street.

Inspector Nicol urged anyone concerned about drug dealing to contact the police immediately.

He said: "Never assume we know about everything that is going on.

"Information from the community is vital to police in tackling drug-related crime."
