A woman and a Schindler Elevator K.K. employee were trapped for 30 minutes Wednesday in a Schindler lift next to the one that killed a 16-year-old boy last month in a Tokyo condo high-rise, Minato Ward officials said.

The resident was descending from the 10th floor of the public housing building at around 11:55 a.m. when the elevator suddenly stopped on the ninth floor, trapping her and the Schindler employee, who was riding the elevator for safety purposes.

The employee and other Schindler staff also on site fixed the problem and no one was hurt, the ward said.

The Japanese subsidiary of the Swiss-based elevator and escalator maker took the elevator out of service and is investigating the cause of Wednesday's problem.

Hirosuke Ichikawa died June 3 after becoming wedged between the elevator floor and the upper frame when the elevator, with doors still open, suddenly ascended as he was getting off on the 12th floor.
