A Japanese man accused of taking pictures up a woman's skirt stabbed two court officers Friday as the verdict in his sex pest case was being delivered, a court spokesman and media said.

Seiji Yodogawa, 30, reportedly yelled "what a rotten justice system" as he lunged at the two officers standing in the court gallery and slashed them on their face and back with a hidden knife.

Yodogawa was immediately taken into custody on attempted murder charges, the spokesman added.

The two policemen were sent to hospital with non-life threatening injuries, Japan's public broadcaster NHK reported.

The courtroom drama erupted just as the judge was delivering a verdict in Yodogawa's upskirting case.

He had been charged over allegations he secretly took pictures under a female train passenger's skirt in Sendai, a coastal city north of Tokyo.
