A 1-year-old boy survived a 10-story fall from a Tokyo apartment building Thursday after his disturbed father allegedly tossed him out a window in the morning, police said.

The baby survived after landing on shrubbery and escaped with slight facial cuts. His father, Shingo Hashimoto, 37, was then arrested at the Koto Ward property after calling the police to confess.

"I tried to kill my son. I tried to strangle him with my hands and dropped him" out of my bedroom window at 9 a.m., the police quoted the company employee as saying.

The police said the baby did not sustain any life-threatening injuries and added that Hashimoto, who lives with his wife, 38, and a 4-year-old daughter, called the police himself after the incident.

Hashimoto will undergo psychiatric tests to determine whether he was mentally sound at the time. His family told police that he seemed "distressed by work" recently.

Hashimoto's wife, daughter and mother-in-law were away from the 12-story building at the time, police said.
