A noted Cuban blogger says she was worked over in a "professional" manner this week while on her way to a Havana protest rally.

"No blood, but black and blues, punches, pulled hairs, blows to the head, kidneys, knee and chest," Yoani Sanchez told El Nuevo Herald shortly after the Friday incident. "In sum, it was professional violence."

Sanchez said she and fellow blogger Orlando Luis Pardo were accosted by a trio men she assumed were Cuban plainclothes security officers prior to the anti-violence march.

Sanchez is a popular online commentator whose "Generation Y" blog takes frequent digs at the Cuban government.

She told the Miami newspaper she and Pardo were hustled into a waiting car and driven around for about 20 minutes before being pushed out on to a street in another part of town.
