Two Chinese managers, including the local managing director, were taken away by police for questioning yesterday, the company said in a statement.
"The allegations are not known in detail, but could relate to investigations into employees of the Chinese sales organisation," the statement said.
"This primarily concerns embezzlement to the detriment of Schindler, as well as passive bribery (acceptance of bribes), and possibly bribery relating to private individuals."
China-based staff of Schindler declined to comment on the allegations.

British drug marker, GlaxoSmithKline (GSK), was fined around USD 490 million by a Chinese court last September following a nearly year-long bribery probe.
The court ordered the firm's former head of China operations, Mark Reilly, to be deported, and sentenced four other former GSK executives to between two and four years in prison, state media have reported.
Schindler said it is working closely with authorities on the case and will provide further information as soon as "proven facts" have been established.
