MIAMI (AP) - Authorities say Marleine Bastien, an advocate and candidate for Congress, was robbed at gunpoint while waiting to make a campaign appearance at a church in North Miami.

Lt. Neal Cuevas with the North Miami Police Department says Bastien was in a car with her sister outside the Church of the Living God Saturday when another car pulled up along side them.

A man got out of the vehicle, opened the driver's door, where Bastien was sitting, and demanded that the women give him their purses and threatened to kill them.

Cuevas says the man then took off. Investigators believe he was involved in a similar robbery 30 minutes earlier.

Bastien is one of four Haitian-born candidates running in a Democratic primary next week for an open House seat in a South Florida district.
