A topless woman who interrupted the Latvia-Portugal World Cup qualifier by running onto the field and hugging a Portuguese defender was charged with hooliganism, Latvia police said on Monday.

She faces up to two years in jail, community service or a fine.

As is customary in Latvia, police identified the woman by her first name, Liene, adding that she went by the nickname "Strawberry.''

Her topless run in the 54th minute of Saturday's game drew a roar of approval from the crowd but appeared to unsettle the Latvian team as Portugal scored two goals just minutes after play resumed. Latvia lost 2-0.

The streak, the first at a Latvian soccer game, appeared to leave police unsettled, too. The woman waited on the field for nearly a minute before officers escorted her off.

Portugal coach Luiz Felipe Scolari, who was shown on television laughing through the incident, jokingly credited the woman's run as the game's turning point.

But Latvian prosecutors and soccer officials weren't amused. A court date was not announced.

Liene told police she ran on the field in the name of art, saying it made her happy to have brought so many

smiles to the fans and to Scolari.

Fans on the popular Latvian Web forum Delfi thought the charges were severe.

"This is funny, but it's actually tragic,'' wrote one contributor calling himself Cidons. "For an action that didn't harm anyone and made people laugh they're going to open a criminal case?''

Another thought Latvia should learn from the incident.

"When we play in Portugal we need to get a Portuguese Strawberry to run on the field to mess with the minds of their locals. Then we'll score three goals,'' wrote a contributor calling himself Smins.
