"Information about written evidence being found during searches, published today by British tabloids, is not true," a spokesman for the investigative team told reporters.
The spokesman added that the police had gathered evidence in the home of the co-pilot, which will be further investigated, though refrained from providing further details.
On Thursday, a French prosecutor asserted that according to data from the aircraft's first black box, the captain left the cockpit to visit the toilet, and the co-pilot then locked the captain out.
The co-pilot is said to have showed no signs of panic and is deemed to have been conscious while he was alone in the cockpit. The prosecutor said that the passengers were unaware of the situation on board until the very last minute.
Lufthansa CEO Carsten Spohr said later on Thursday the company believed the plane crash was deliberate. He added that Germanwings pilots did not undergo regular psychological evaluations and only took a psychological test during training.
