Police stormed a Dundee multi in an early-morning drugs bust.
Officers battered down a door in the Lansdowne Court multi-storey block in Dryburgh.
A property on the second floor is believed to have been targeted as officers executed a search warrant.
Police Scotland confirmed it was carrying out an investigation in relation to the raid — but did not reveal if any items were seized or if any arrests were made.
A witness said police had targeted the property early Friday – with multiple units at the scene.
She said: “I heard a lot of commotion downstairs.
“I looked out and there were police all around the bottom of the block.
“They went up to the second floor and there was a bang and some shouting — I thought it was a drugs bust straight away.
“The police are always up here. They have been here loads of times in the last few months and usually it is drug-related.
“I keep myself to myself but you notice it when they are here.”
She added: “This area is getting worse and worse.”
The resident said police remained at the scene for a number of hours and were seen going back and forth between vehicles and the property.
A police spokesman said: “Police Scotland can confirm that a drugs search warrant was executed at a flat in Lansdowne Court yesterday.
“Inquiries relating to this are ongoing.”
The raid came as officers continue to crack down on the distribution of drugs as part of Operation Slate, which was launched across Tayside three years ago.
On average, officers seize substances worth more than £1 million every year.
Suzie Mertes, partnerships superintendent at Tayside Division, said earlier this month that officers would continue to target dealers through the operation.
Supt Mertes was speaking in response to a Tele investigation that revealed 72 people had been victims of suspected drug-related deaths between April last year and March this year.
