TORONTO - A 20-year-old Montreal woman has filed a lawsuit claiming she was shot twice with rubber bullets while protesting at June's G20 summit in Toronto and threatened with rape while in detention.

Natalie Gray launched the suit Tuesday in Ontario and is seeking more than $1.6 million in damages.

Gray claims she sustained extremely painful injuries to her elbow and sternum when hit by what she believes were rubber bullets while peacefully protesting on June 27.

Gray claims was charged with obstruction of a peace officer and says she was driven around in a police car for 30 minutes begging to be taken for medical help before she was taken to hospital to receive treatment.

The Crown withdrew the charge against Gray on Aug. 23 and she is claiming assault, unlawful arrest, malicious prosecution, and violations of her rights under the Charter of Rights and Freedoms -- none of which have been proven in court.

Gray's lawyers, Clayton Ruby and Brian Shiller, are calling for an immediate criminal investigation of the police officer alleged to have shot her.

Gray's civil action claiming mistreatment by police on June 27-28 names the Toronto Police Services Board and unnamed individual police officers.

According to Gray's statement of claim, an officer "standing no more than five metres from her aimed his deadly weapon at the plaintiff and shot her twice" on June 27.

"She experienced tremendous pain from the impact of the projectiles and her skin was torn off," the statement says.

Gray says she repeatedly begged to be taken for medical help and claims a sergeant told her to "stop whining."

After being treated in hospital, Gray said was taken to the detention centre set up to handle G20 arrests and sent for a strip search.

When she was asked to remove her piercings, Gray said she told officers she couldn't do so without pliers.

"The officers told her she better try harder or else they would cut them off," the statement of claim alleges.

The officers left the piercings in.

The next day, after being returned from court, Gray claims an officer made a comment about "banging" her.

"The plaintiff took this to mean that the officer was threatening to rape her," the statement of claim says.

Gray was "arbitrarily detained, subjected to cruel and unusual punishment and had her rights to peaceful assembly, liberty and security of person denied to her for no lawful purpose," the claim states.

Two class-action lawsuits have also been launched in the aftermath of the G20 summit.

More than 1,000 people were detained by police that weekend after protesters using so-called Black Bloc tactics broke away from a peaceful rally and ran through the city's downtown core, smashing windows and burning police cruisers.

The vast majority of those detained were released without charge within 24 hours. Some spent the night in a film studio that was converted into a temporary detention centre.
