The police said the woman shooter has been taken into custody.

The incident reportedly occurred during the Rock 'n' Roll Marathon.

The police tweeted: "The Active Shooter at 100 West C St. is in custody. There’s no longer a threat to the community. The scene is secure. The Rock and Roll Marathon has resumed."

No injuries have been reported so far.

The organisers of the race said in a statement as quoted by BBC: "The situation involving an active shooter who was engaged with law enforcement was not related to today's race."

"By 11:45 (18:45 GMT), the course was shut down and approximately 4,900 athletes were rerouted into a designated safe zone," it read.

"While the race was officially stopped, law enforcement gave the clearance at 11:56 for runners to resume their progress toward the finish line and the post-race finish area, where they were able to meet up with family and friends," read the statement.
