Washington, April 29 : A Los Angeles Superior Court judge has issued a three-year restraining order against Britney Spears' former manager Sam Lutfi.

Attorneys for Britney's father and conservator, Jamie, had been seeking a long-standing restraining order against Lutfi, the singer's ex manager and close confidant during her personal meltdown.

And now, Judge Aviva Bobb has ordered Lutfi to keep at least 100 yards of distance from the singer, her two sons and her family members'' homes.

He further must not hassle the pop princess and her kids, or try to contact them through phone, mail and email.

The orders also forbid him from "acting on Ms. Spears''s behalf or purporting to act on her behalf."

Lutfi''s lawyer Bryan Freedman said he would contest the judgement.

"We absolutely will appeal this ruling. Never before in history has a restraining order been issued against someone who answered another person''s cries for help," People magazine quoted him as saying. (ANI)
