Washington owner Dan Snyder said he supports an "unbiased investigation" after 15 women who previously worked for the franchise alleged they were subjected to sexual harassment from team employees.

The women, only one of whom - Emily Applegate - was willing to go on record, made accusations against former scouts and members of Snyder's "inner circle" in an article by The Washington Post.

Attorney Beth Wilkinson confirmed her firm, Wilkinson Walsh, had been hired by the team to review the allegations.

In a statement, Snyder said: "The behaviour described in yesterday's [Thursday] Washington Post has no place in our franchise or society.

"This story has strengthened my commitment to setting a new culture and standard for our team, a process that began with the hiring of Coach [Ron] Rivera earlier this year.

"Beth Wilkinson and her firm are empowered to do a full, unbiased investigation and make any and all requisite recommendations.

"Upon completion of her work, we will institute new policies and procedures and strengthen our human resources infrastructure to not only avoid these issues in the future but most importantly create a team culture that is respectful and inclusive of all." 

The NFL earlier released a statement, which read: "These matters as reported are serious, disturbing and contrary to the NFL's values.

"Everyone in the NFL has the right to work in an environment free from any and all forms of harassment."
