Sam Lutfi still banned from going near Britney Spears

The restraining order banning Sam Lutfi from going near Britney Spears has been extended by a federal judge.

Legal papers show the order keeping Lutfi away from Britney will now run until March 17. It means he cannot even make phone contact with the popwreck.

The judge also ruled Lutfi was properly served with the legal papers from her parents Thursday.

Lutfi managed to dodge authorities for almost three weeks though before they finally caught up with him at his LA house.

Britney's mum Lynne claimed in the restraining order Lutfi drugged her daughter. She described a chaotic night at Britney's Hollywood Hills home where the popwreck was led around in a drugged and confused state by Lutfi.

Lynne's statement claimed Lutfi had "drugged Britney, he has cut Britney's home phone lines and removed her cell phone chargers".

But police insist they are not investigating the claims despite reports robbery and homicide officers are on the case.

LAPD Media Relations representative Richard French said: "There is no investigation into Sam allegedly medicating Britney."
