Two men posing as parcel deliverymen shot and seriously wounded a 75-year-old man at his home Friday in Musashimurayama, western Tokyo, police said.

Teruhito Tanabe was shot several times in the abdomen and chest after opening his front door to the men at about 11:30 a.m., police said. He was taken to a hospital.

The two attackers fled the scene immediately, according to an employee at a nearby store who witnessed the shooting.

Police said one of the men is in his 20s or 30s, between 170 cm and 180 cm tall, and was wearing black clothes and a cap at the time of the incident.

Tanabe called police himself after being shot and reportedly told them he was shot immediately after opening the door.

Tanabe lives with his family, but was home alone at the time of the shooting. His house is in a residential area near Seibu Tachikawa Station on the Seibu Haijima Line, police said.

In a similar attack on the evening of June 9, a man posing as a parcel deliveryman, believed to be in his 20s, visited the home of building contractor Toshiharu Maruyama in Tokyo's Itabashi Ward and shot him dead after he opened the door. Maruyama, 70, was also shot in the abdomen.

On June 4, another duo stormed into a 33-year-old man's house in Tokyo's Katsushika Ward and shot him dead.
