Police Investigating Britney Subpoena Run-In
Aaron Cohen – the former Israeli commando who previously served Spears's assistant Alli Sims, among others – attempted to serve papers near Lufti's Los Angeles home.
According to one version of events from Federline's camp, Lufti apparently became alarmed, and repeatedly rammed his silver Mercedes-Benz SL500 into Cohen's black Range Rover and his assistant's Buick Park Avenue. The impact caused at least one tire on Cohen's Range Rover to pop.
However, Lufti tells PEOPLE that he was "surrounded by three cars and was hit from the front, back and right side of my car. If I did hit anyone, it would have been in self-defense. I was just trying to get to the police."
The incident "is being investigated as an assault with a deadly weapon with a vehicle," says Los Angeles police Officer Mike Lopez. "Detectives are still looking into the case."
Cohen had no comment at the scene.
This was the latest of several subpoena attempts by Federline's legal team, headed by attorney Mark Vincent Kaplan. Sims, Spears's former assistant Shannon Funk, bodyguard Daimon Shippen and an executive administrator from the Promises rehab facility have all been served.
