Drugs were seized and multiple people were detained as police carried out drugs raids in Dundee.
Officers swooped on addresses in the Stobswell area of the city, forcing entry to flats.
Police with riot gear and dogs descended on a property in Fairbairn Street at about 9am on Tuesday. Several people were taken into custody, but the final number was still to be confirmed.
A man and a woman were seen being led from the block wearing handcuffs.
It came less than 24 hours after police seized cannabis plants from a flat in Baldovan Terrace.
A police spokesman said: “Police Scotland can confirm that a drugs search warrant has been executed on Tuesday at a flat in Fairbairn Street, Dundee.
“A number of persons have been detained from the address and inquiries are ongoing.”
He added: “Police Scotland can confirm that a drugs search warrant was executed at a flat in Baldovan Terrace on Monday.
“A quantity of drugs were recovered, and inquiries are ongoing.”
One scaffolder working at the block in Fairbairn Street said he had been told to stop working by police while investigations were carried out.
The man, who asked not to be named, said: “Police arrived about 9am. There were loads of them. They all piled in the close.
“We saw a few folk being taken away in handcuffs.
“There were six cars and a riot van and sniffer dogs too.
“We were told by police we weren’t allowed to work and they were searching all the scaffolding out the front and back of the flats.”
A Dundee City Council worker arrived at the scene at about midday and told the Tele he was there to repair a door that had been rammed by police.
The raid in Baldovan Terrace took place at about 2pm on Monday with officers still on the scene into the evening.
No arrests have been made in connection with the bust but cannabis was seized from the flat. One resident told of seeing officers carrying a battering ram entering the block, followed by “really loud banging”.
Meanwhile Doreen McHugh, who lives nearby, said: “I was heading out around 2pm and there were three police vehicles, including two riot vans, outside.
“The police were in the tenement.
“It looked like they may have been looking for someone or something.”
Fellow resident David Cornish, 57, told the Tele: “Police seemed to have spent a lot of time there.
“I think they also went into the flats next door.”
