October 14 [10:00 EDT] -- The R&B vocal trio Total held a press conference in Washington, D.C. on Monday to announce that the group is suing Amtrak for $50 million after an incident involving Da Brat, Amtrak Police, and pepper spray.

Total charges the railroad with assault and battery, false arrest, and false imprisonment in an incident that occurred two weeks ago in D.C.'s Union Station (and which we first reported on earlier this month, see "Da Brat Threatens Suit After Amtrak Arrest" in the MTV News Gallery).

The group was there with Da Brat when Amtrak's Federal Police charged them all with disorderly conduct and sprayed them with pepper spray. Amtrak claims the action were taken because Total and Da Brat started singing loudly after being asked to turn down their radio, and that one of the bodyguards with the entourage then made a menacing motion prompting the pepper spray.

Total says the officer took deliberate aim at them, and that they were even asked to remove their pants to be searched.

Da Brat is currently out of the country, but shortly after the incident she said she was planning a suit of her own.

Amtrak says that Da Brat and two members of Total paid their fines without complaint, and is consequently perplexed by the suit.
