SUITA, Osaka Prefecture--A police officer here was seriously injured on June 16 after he was stabbed by a man who fled the scene with his service revolver, in a possible ambush as police were responding to a false burglary call.

The 26-year-old police officer was stabbed several times and found lying bleeding on the street near the Suita police's Senriyama police box around 5:40 a.m. A station employee at Senriyama Station of Hankyu Corp.’s Senri Line alerted police about the attack.

The perpetrator is believed to be a man in his 30s. He took the officer's revolver, which was loaded with five bullets.

Police set up a task force to investigate the case, handling it as an attempted robbery and murder case.

“We are sorry to cause anxiety to the public,” said Takahisa Ishida, chief of the Osaka prefectural police. “Please stay alert and call us if you spot anyone suspicious.”

According to police, the wounded officer was working his shift with two male superiors, who are 44 and 33.

Around 5:30 a.m. that day, a man reported a burglary to police from a payphone from a store near the platform of Senri Line’s Kandai-mae Station.

As the crime scene fell within the jurisdiction of the Senriyama police box, the two older officers rushed to the scene by motorcycle.

The younger officer was stabbed by a man after he came out from the police box with investigation equipment to join his superiors in responding to the call.

When the officer was found, a knife was stuck in his left chest, and he had been stabbed several times.

He told a colleague before he was rushed to a hospital that a man attacked him and stole his gun. The officer was conscious when he was transported to a hospital, but was later reported in serious condition.

When police investigated the apartment where the burglary was reported, they found no sign of damage or wrongdoing.

Police said there is a possibility that the man who called police made a false report and ambushed the officer.

Footage from a surveillance camera near the police box showed a man who appeared to be in his 30s in a white T-shirt and black jacket and trousers pacing back and forth.

Police believe that the man has knowledge of the attack on the officer.
