SEOUL, South Korea—Enraged protesters threw eggs at the brother of South Korea's president Tuesday, grabbing his tie and jostling him as he entered a court for questioning over corruption allegations.

A Seoul court said it was reviewing whether to arrest President Lee Myung-bak's brother, and it expected to make a decision later Tuesday.

Prosecutors accuse former lawmaker Lee Sang-deuk of taking half a million dollars in bribes from two detained bankers. On Friday, prosecutors requested the Seoul Central District Court approve his arrest.

Lee Sang-deuk wasn't directly hit by any of the eggs, but some yolk could be seen on his shoulder. He didn't speak to a swarm of reporters gathered at the court, shaking off the protesters and media mobbing him before walking through a security checkpoint.

The protesters said they'd lost money after the government suspended the troubled savings banks Lee is accused of taking bribes from.
