Cars were vandalised on Tuesday in a suspected attack targeting photographers outside the home of Giggs.
A group of masked men damaged the body work, slashed tyres and egged the vehicles parked near the footballer's mansion in Worsley, Greater Manchester.
Press attention on Giggs, 37, intensified yesterday when he was named in Parliament as the married footballer involved in a controversial privacy case.
Six cars were targeted shortly after 3.20pm in Worsley, Greater Manchester Police (GMP) said.
Several men wearing balaclavas burst out of a Ford Transit van and attacked the vehicles before fleeing the scene.
A police spokesman said officers attended and inquiries are continuing.
