Four men have been arrested after armed police descended on a harbour this morning.

Firearms officers arrived at Ramsgate’s waterfront at about 8am alongside ambulances.

A witness also described seeing several unmarked police vans and a medic car at the time.

It was later revealed that Border Force had stopped a fishing boat out at sea and found a massive drug haul.

National Crime Agency (NCA) officials have arrested four men and seized approximately 400 kilos of cocaine.

Three men on board, aged 64, 45 and 25, were arrested on suspicion of importing class A drugs and were taken to police custody to be questioned by NCA investigators.

A 36-year-old man was also arrested in Rainham, East London.

NCA operations manager Jules Harriman said: “This amount of cocaine will represent a significant loss for the organised crime group that attempted to import it into the UK.

“With our partners at Border Force and the Joint Maritime Security Centre (JMSC), we have successfully removed this harmful drug consignment from the criminal marketplace.

“Our investigation into this importation continues.”

Danny Hewitt, director of Border Force National Operational HQ added: “This is a significant seizure and demonstrates how Border Force work closely with partners at the National Crime Agency to stop these toxic drugs from hitting our streets in the first place.

“We continue to work tirelessly to protect our borders and keep the public safe.”
