    The BART police officer who fatally shot an unarmed man on an Oakland train platform and then refused to explain his actions to investigators was arrested Tuesday in Nevada on suspicion of murder, authorities said.

    Johannes Mehserle, 27, was arrested in the New Year’s Day shooting of Oscar Grant, a 22-year-old supermarket worker from Hayward who was lying facedown after being pulled off a BART train by police investigating a fight. An Alameda County judge signed an arrest warrant alleging murder, and Mehserle surrendered without incident, authorities said.

    The shooting, which was recorded by passengers in videos widely circulated on the Internet and television, prompted public outrage, and some viewers said that the shooting appeared to be an execution.

    Sources said Mehserle was in Nevada because he feared for his safety after death threats were made against him. Douglas County is 15 miles south of Carson City in northwestern Nevada and includes part of Lake Tahoe.

    Grant’s family has filed a $25 million legal claim against BART, signaling an intention to sue for damages. The family’s attorney, John Burris, said late Tuesday that he was pleased to hear of Mehserle’s arrest.

    “If it’s true, the family is delighted, and it will really help with the healing process,” Burris said. “This is also very important for the community. This had to occur; it was almost a no-brainer. I think the district attorney ought to be commended for moving (the case) expeditiously.” LINK
