The Tampa Bay Lightning suspended defenseman Ian Cole indefinitely Sunday after a woman said he sexually assaulted her when she was a minor and groomed her over a four-year period.

"The Tampa Bay Lightning is aware of the allegations against player Ian Cole and are cooperating fully with the NHL on an investigation," the team said in a statement.

"Our organization takes these allegations very seriously. While we continue to gather more details, we have decided to suspend Ian Cole pending the results of an investigation. No members of the organization, including players, will comment further at this time."

On Friday, a Twitter user with the name Emily Smith posted a statement saying Cole sexually abused her, including sexually assaulting her when she was a minor.
