An armed assailant fatally shot three individuals at a maritime shipping company's headquarters in a coastal suburb Athens, Greece on Monday, before taking his own life, according to a Greek police source.
The gunman stormed into the building of "European Product Carriers" located in the "Glyfada" area, where he killed two men and a woman before barricading himself inside, the source reported.
Greek media outlets have identified the shooter as a former employee of the company who had been dismissed. He was later found deceased in the basement with his weapon by his side.
Police sources suggest preliminary findings indicate the shooter committed suicide.
Earlier, the police had reported that their officers entered the building and rescued two women who had been confined by the gunman in the restroom facilities.
The vicinity was cordoned off, with a significant police presence surrounding the building.
Founded in 1979, "European Product Carriers" boasts an average fleet of 35 cargo ships, according to the company's website.
Many Greek and international shipping companies have their headquarters in "Glyfada," a coastal resort south of Athens, and in the main port of "Piraeus," near the capital.
