This is the dramatic moment police in Russia arrested a suspect in the killing of a submarine captain.

Footage shows armed officers storming a house in Tuapse, in the southern region of Krasnodar, smashing the windows in their search for Sergei Denisenko.

‌The 64-year-old was seen cowering on the kitchen floor in his underwear as forces pointed their firearms at him.

He is accused of gunning down Stanislav Rzhitsky, a former Naval officer, on Monday morning in the city of Krasnodar.

Several Russian media outlets speculated the 42-year-old may have been tracked via his profile on the Strava fitness app.

His address, picture and personal details had appeared on the Ukrainian website Myrotvorets (Peacemaker), a vast unofficial database of people considered to be enemies of Ukraine.

Earlier today, the word ‘Liquidated’, in red letters, had been superimposed on his photograph on the site.

Ukraine’s GUR military intelligence agency published details of the incident on its website, without claiming responsibility or saying how it obtained the information.

It said Rzhitsky died on the spot when an assassin fired seven shots at him from a Makarov pistol as he was running in a deserted city park at around 6am.

The statement read: ‘The submariner was jogging in the 30th Anniversary of Victory park in Krasnodar.

‘Around 6 am he was shot seven times with a Makarov pistol. As a result of the gunshot wounds, Rzhitsky died on the spot.

‘Due to heavy rain, the park was deserted, so there were no witnesses who could provide details or identify the attacker.’

Ukraine’s military intelligence chief Major-General Kyrylo Budanov today issued a statement to deny his agents were responsible for the killing, which he blamed on internal Russian anti-war activists.

‘We know that the roots of what happened yesterday in the Russian Federation must be sought within Russia itself, where internal protest against the war in Ukraine is growing,’ he said.

Russia’s state Investigative Committee confirmed it had arrested a suspect in his early 60s who was found in possession of a pistol and silencer, along with money, and posted the video.

Denisenko, a karate teacher who was born in Ukraine and still has connections there, is now being interrogated as a ‘suspect’, the committee said.
