LONDON, ENGLAND - SEPTEMBER 25: Used cars by German manufacturer Volkswagen are parked at a dealership in Battersea on September 25, 2015 in London, England. The Department for Transport's Vehicle Certification Agency, the UK's national approval authority for new road vehicles, has announced that it will re-run laboratory tests on engines and compare the results with emissions from on-the-road tests in the wake of the VW test-rigging scandal. The German car manufacturer has admitted selling vehicles in the US with diesel engines that could detect when they were being tested for emission, changing the vehicles performance accordingly in order to improve results.

LONDON — German police raided 28 homes and offices this week as they widened an investigation into Volkswagen’s diesel emissions scandal.

Former CEO Martin Winterkorn stands accused of knowing about the emissions cheating way before the company came clean. He is being investigated for fraud.

“There is sufficient reason to believe that [Winterkorn] was aware of the manipulating software and its effect earlier than he publicly claimed,” the state prosecutor said in a statement, referring to confiscated documents and statements from witnesses.

Winterkorn resigned after the scandal became public. He has said he was stunned by the scale of the misconduct. In his resignation statement, he accepted responsibility for the scandal, but insisted he had no knowledge of the manipulation of emissions tests.

Volkswagen said it was cooperating with the authorities, but did not comment on the probe into Winterkorn.

Prosecutors first labeled Winterkorn a suspect in late September 2015, only to reverse position a few days later. In June 2016, they said they were investigating him for manipulating the market in Volkswagen shares.

On Friday, they added the accusation that he knew about the scandal.

The prosecutor said the number of people under investigation has now risen to 37, including Winterkorn.

The news follows a decision by U.S. federal investigators to arrest Volkswagen’s former head of regulatory compliance in the U.S. and charge five other officials.

Volkswagen has agreed to pay $4.3 billion in federal fines and took the unusual step of pleading guilty to criminal charges in the U.S.

Volkswagen admitted in 2015 that it fitted as many as 11 million diesel vehicles worldwide with software that could cheat nitrogen oxide emissions tests.

On Wednesday, the carmaker said that the board member in charge of “integrity and legal affairs” would be leaving the company after just over a year in the post because of a difference of views.

Former German supreme court judge Christine Hohmann-Dennhardt was brought in to help the company raise its compliance standards following the emissions scandal.
