DENVER -- A University of Denver law professor said an Uber driver tried to take her to a hotel against her will instead of the airport on Tuesday.
In a series of tweets, Nancy Leong described the incident where the driver said he was going to take her to a hotel and that he refused to unlock the doors to let her out.
The incident happened at 56th Avenue and Pena Boulevard, Leong said.
Leong tweeted that she started pounding on the windows and that the driver unlocked the doors when construction workers who were installing a traffic light at the intersection noticed.
When she got out to get her suitcase in the trunk, the driver allegedly started coming toward her until the car started rolling into the intersection.
Leong said the driver ran toward the car and quickly drove away.
She added the construction workers waited with her until another Uber driver arrived.
Uber said in a statement the driver has been blocked from the app and that it is investigating the incident.
"What Nancy described is awful and unacceptable. This driver has been blocked from the app and we are investigating," Uber said.
Uber added the driver had been a driver for more than a year. The Denver Police Department said it has not received a report from Leong.
Leong declined a request for an interview.
On Thursday, Uber CEO Dara Khosrowshahi announced major safety-related changes coming to the company, including equipping riders to identify five people as "trusted contacts" who will receive trip details during every ride.
Uber said the app will include an emergency button that connects a rider directly to 911. The feature will show the rider's real-time location that can be shared with a 911 operator.
Additionally, Uber said it will strengthen driver screening.
