Police have disrupted a major county lines drug network between the South West and North West of England.
The two-day operation involved officers from Plymouth and the Project Medusa team from Merseyside and led to 46 arrests.
Officers seized heroin, crack, cocaine, cannabis and spice during a series of targeted raids – one of which saw officers use a chainsaw to gain access to a property.
Of those arrested, nine have been charged, three issued with cautions, and others were released under investigation or police bail, pending further enquiries.
A number of those arrested were from the Plymouth area but others were from outside the area.
Chief Superintendent Matt Longman, commander for Plymouth, said: “A lot of planning has gone into making sure we have a really proactive week and make the biggest impact we can on dangerous drug networks and county lines that supply drugs into the city.
“This has been a very successful operation and I’d like to say a huge thanks to Merseyside Police, British Transport Police and our officers here in Plymouth.”
Police and Crime Commissioner Alison Hernandez said: “Drugs are a scourge on our society.
"They have a devastating impact on individuals, families and businesses in communities across Devon, Cornwall and the Isles of Scilly.
"Our communities are frustrated by blatant drug dealing and using, which is why I have made tackling drugs a major priority in my police and crime plan."
