Brad Pitt has secured a restraining order against Vitalii Sediuk.

The 50-year-old star, who was allegedly hit in the face by the Ukrainian prankster while attending the Hollywood premiere of his fiancée Angelina Jolie's new movie, 'Maleficent,' last night (28.05.14), obtained a temporary emergency protection order today (29.05.14), forcing Sediuk to stay at least 500 feet away from him for the next five days.

The 25-year-old reporter, who was placed on probation for three years after trying to interrupt Adele's speech at the Grammy Awards in 2013, could also face criminal prosecution for attacking the actor and breaking his designer sunglasses.

A law enforcement source told gossip website TMZ.com that a file has been sent to the Los Angeles City Attorney.

Sediuk - who claims to work for 'Studio 1+1,' a website and channel in his native country - has become known for pranking celebrities on the red carpet.

Last week he attempted to put his head up 'Ugly Betty' actress America Ferrera's skirt at the Cannes premiere of 'How To Train Your Dragon 2'.

In January this year, he hugged Bradley Cooper around the waist, putting his face in the 'Hangover' star's crotch at the Screen Actors Guild Awards, and a month later, tried a similar move on Leonardo Dicaprio at the Santa Barbara Film Festival.

Sediuk was also involved in an angry encounter with Will Smith at the 'Men In Black 3' premiere, two years ago, after he tried to kiss the star on the lips.
