THIS is the horrifying moment a coldblooded assassin guns down a rail passenger in a packed station.
The killer sneaks up behind the man, 27, before shooting him in the head and walking away.
CCTV footage shows that the suspect opened fire at point blank range causing his victim to collapse on the ground with little chance of survival.
After hearing the loud bangs dozens of passengers on the platform then began running for their lives.
After the first shot the assassin then moved closer to the injured man – who was splayed out on the floor – and fired several additional shots.
He then attempted to flee the site and cast his weapon aside.
Police caught the man a few metres away from the crime scene on the nearby platform seven, and arrested him without resistance.
The murder weapon was discovered during a search later.
The station was closed to all train traffic for about 25 minutes until the police operation was completed.
Frankfurt am Main Police Headquarters said in a statement obtained by Newsflash: “Help came too late for the 27-year-old, who died at the scene.
“Both men are Turkish citizens.”
Police are now investigating whether the two men knew each other and are working to determine a possible motive for the shooting.
Frankfurt Public Prosecutor’s Office spokesperson Dominik Mies said: “The investigation is still in its early stages, so I ask for your understanding that we cannot yet say anything about the motive or the relationship between the suspect and the victim.”
Police said: “The 54-year-old suspect will be brought before the investigating judge of the Frankfurt am Main District Court today by the public prosecutor’s office, who will have to decide whether to order him in custody.”
The footage triggered an avalanche of reactions on the social media platform X, leaving users unable to hold back from commenting.
One X user said: “The greatest plague of humanity. The religion of coercion.”
Then another added : “This is so disturbing and brutal!”
And a third said: “That was an execution!”
