Denver Police say Noel Alexander Bertrand faces charges of felony sexual assault.
Investigators say the 22-year-old alleged victim was traveling through DIA when she met Bertrand.
The two were both at an airport bar together, according to police. Later when the bar closed just before 1 a.m., police say Bertrand forced himself on the woman and tried to assault her on the floor of Concourse A.
He was taken to the Denver County Jail and is being held in lieu of a $10,000 bond.
DIA spokesperson Jenny Schiavone says a contracted security guard called 911.
Police say airport workers detained Bertrand until officers arrived.
Schiavone says the airport is safe and there are many layers of security. She called it "a safe environment."
Bertrand's picture is not being released pending a line up.
Records show he is from Portland, Oregon. 9NEWS called his home in Oregon and the woman who answered the phone would not identify herself. She told us Bertrand is a former Marine.
On Wednesday, DIA released a statement regarding the sexual assault:
"We are taking the alleged sexual assault that occurred at DIA on April 12 very seriously. The airport is fully cooperating with the Denver Police Department's ongoing investigation. To the best of our knowledge, airport employees who witnessed the incident responded immediately by either calling for help or intervening in the situation. We are asking anyone who may have information about the incident to contact the Denver Police Department.
We strive to make Denver International Airport the safest environment as possible. All airport employees complete a mandatory annual training on safety and security in order to have their badges renewed. Employees are trained to be extra-vigilant and to report suspicious activity using an emergency phone number printed on all badges. In addition to this protocol, the traveling public is asked, via overhead announcements, to report suspicious activity by using phones located on the concourses and in the terminal. DIA has many layers of security including local and federal law enforcement, as well as security guards that are privately contracted by the airport. Safety and security is of the utmost importance at DIA, and police and security patrol the premises including Jeppesen terminal and all concourses."
