Adrian Sutil could yet face legal proceedings as a result of the nightclub incident that left Genii Capital's Eric lux nursing a head injury - and that, in turn, could place his F1 future in jeopardy.

Initial sources claimed that a row between the pair in a private VIP room - apparently the result of Lux telling Sutil to 'calm down' - culminated in the German striking Lux with either a glass or bottle, leaving the Renault F1 investor with blood streaming from a neck wound.

Now, a source close to Crash.net reveals that the incident was sparked by a row over Lux's girlfriend, with the Genii CEO apparently upset at the attention Sutil was showing her. Having previously told the young German to 'back off', a second attempt to warn him about his behaviour resulted in a champagne glass being thrown in Lux's direction, cutting his neck.

Sutil immediately issued an apology for the incident, without revealing the details of what happened, insisting that it was an accident rather than deliberate, but Lux's lawyers have now confirmed that, having felt that the incident 'could have killed him', he would be pressing charges against the Force India driver.

"In the view of the recent events which occurred in Shanghai on 17 April, Mr Eric Lux has decided to file a criminal complaint against Mr Adrian Sutil for physical assault and grievous bodily harm," a statement announced, "As soon as the complaint is registered, the FIA and the team Force India will be notified."

In addition to the legal action threatened in the statement, however, Crash.net's source believes that Lux is also suing Sutil for $10m and seeking his removal of his F1 superlicence.

Force India has yet to respond to the statement from Lux's lawyers, but insisted at the time of the incident that it was 'a private matter', while the FIA has said that it is happy to leave the matter in the hands of the relevant authorities rather than getting involved.
