Weapons, drugs and bodies found – but no arrests made
Police divers discovered pump-action shotguns, millions of pounds worth of drugs and three dead bodies in Plymouth's waters.
But don't worry, it wasn't a Mafia invasion – simply an inter-force exercise.
Dive teams from Devon and Cornwall, the Metropolitan police, Avon and Somerset, Sussex and Thames Valley forces, as well as monitors from the Health and Safety Executive, took part in the exercise.
Sgt Andrew Joyner, marine sergeant with Devon and Cornwall Police dive team, said the exercise, held at Princess Yachts' south yard in Devonport, encouraged the separate units to train and work together on a large-scale operation.

He said that by sharing skills and working practices, the teams were better prepared to work with each other on operations such as security during the Olympics and the G8 summit.
Sgt Joyner said: "Each team covers a huge force area and often dive in zero visibility conditions, so you have to know how everyone in the different forces works and have confidence in the surface crews.
"From time to time we're required to go to other areas, so over the last few years the regional teams have got together for these exercises so they're used to working with each other.
"We're a small unit down here, so if a 747 jet crashed into the Sound I would be phoning other units and would want to know what and who I'm getting."
As hosts, the Devon and Cornwall Police team set the scenario for the dive units to complete over the six hours.
Sgt Joyner said: "Underwater police activity is an extension of surface searching, such as missing persons or evidence.
"So the exercise scenario was a vessel, impounded by the UK Border Agency. Various drugs and weapons had been dropped overboard to evade detection.
"In addition, the teams were told three crew members were missing.
"The weapons cache was replica guns seized over the years, while the parcels of drugs would amount to the equivalent of £65 million worth of cocaine."
The 'winners' were Avon and Somerset Police, who recovered all their packages, weapons and bodies.
Sgt Joyner said: "The feedback from the dive teams about the exercise has been really good. Princess Yachts were also absolutely fantastic with their help in allowing us to use their waters."
