The major operation saw four addresses, thought to have links to a crime group, targeted in the Easterhouse area of Glasgow today.
Around 75 officers were involved in the raids which saw four people detained in connection with suspected dealing of controlled drugs. One man was arrested for alleged obstruction.
The operation was the result of intelligence work following a tip-off.
The Evening Times had exclusive access to the operation which saw the homes targeted simul-taneously just after 7am.
A 29-year-old man and three women aged 23, 27, and 37 were detained. As well as the four people being detained, police seized a quantity of drugs and cash.
The haul included a suitcase believed to contain cannabis and one kilo of powder, which could turn out to be around £40,000 worth of cocaine or £10,000 worth of amphetamine.
Chief Inspector Pat O'Callaghan, local area commander, said: "We have had positive results at three addresses.
"Four people have been detained and one man was arrested. We have also had a recovery of a quantity of drugs and cash seizure.
"It has been a very successful operation.
"It is testament to the people of Easterhouse. As a result of their information and working together we have been able to target their issues of concern."
The Evening Times joined the police teams and followed a convoy of officers from the operation base at London Road police station.
Officers including those in uniform and plain clothes gathered for a briefing before setting out in a fleet of 17 vehicles.
We watched as officers struck at two homes in Trondra Place, while two other homes in Torran Road and Dunskaith Street were also targeted.
Officers wearing protective clothing and helmets used battering rams to get into the houses just doors apart.
They broke through a panel in the door and officers crawled through while other officers guarded the back of the premises.
At a neighbouring property, officers struck a door several times before breaking through and climbing into the hallway.
Extensive searches were carried out at the properties in Trondra Place and sniffer dogs were brought in to hunt for drugs and cash stashed in the homes.
One man was led from a property and put in handcuffs before being put in the back of a van. A 33-year-old was arrested in connection with alleged obstruction.
Residents looked out of windows and dog walkers passed by as the officers conducted a full search.
There were also patrols on bikes to reassure the public.
Evidence was brought out of one house including a suitcase believed to contain herbal cannabis worth around £4200 and around £300 worth of cocaine. In another house almost £2000 of cash was seized along with a quantity of drugs, including amphetamine and cocaine worth a combined £700.
At a third address one kilo of white power was found which is to under go testing. It could be found to be around £40,000 worth of cocaine or around £10,000 of amphetamine.
Chief Inspector O'Callaghan said the operation comes on the back of significantly reduced crime figures for the sub division covering Easterhouse, Shettleston and Baillieston.
He added: "We have seen a significant reduction in levels of crime in this area in the past year.
"Crime is down by 20% and serious assaults are down by 30% which if you put that into perspective that is the equivalent number of a class full of pupils.
"When you see there have been 30 fewer people assaulted or injured that makes a massive impact on the community."
