Bullock never met the man she accuses of stalking her

The star asked the Los Angeles Superior Court to place an injunction on Thomas James Weldon, 34, preventing him from going within 200 yards of her.

Bullock alleged that the Michigan man had been continually trying to contact her through e-mail, faxes and phone calls, although she had never seen him face-to-face.

The injunction replaces a temporary one put in place last month after the court heard he wanted to have a "relationship" with the star.

No criminal charges have been filed against Mr Weldon, who was not present in court.

"We just wanted our client protected," said Bullock's lawyer Ed McPherson.

A statement presented to the court said Mr Weldon had a history of psychiatric problems but refused to take any medication.

"Hopefully he will get some help and not fixate on Ms Bullock," Mr McPherson said.

Bullock became a major star after appearing in 1994 thriller Speed, and has remained one of Hollywood's most bankable actresses.

Her other roles include the comedy Miss Congeniality and While You Sleeping.
