Russia tennis player Anna Chakvetadze escaped unharmed after several men broke into her house in southwest Moscow early on Tuesday.

"Five to six unknown people wearing masks climbed over the fence of the country house at about 4:00 a.m. Moscow time (0100 GMT), then broke into the house and tied her parents up," a police spokesman said.

"They took money and valuables worth some five million roubles (over $200,000)."

World number six Chakvetadze has won four singles titles this year, earning more than $1.4 million in prize money.
