Last week, Fox Sports reported that Major League Baseball is investigating players at the Rangers’ Dominican academy for an alleged sexual assault, but not many details were known. On Monday, Yahoo Sports’ Jeff Passan released information he obtained about the incident, and it’s pretty heinous.

Passan reports a source told him the alleged assault involved “four players who held down a teammate and masturbated him.” Passan also says he obtained a short 10-second Snapchat video of the incident and he described it as such:

Yahoo reports eight players in total were questioned by police, including the younger brother of Rangers second baseman Rougned Odor (also named Rougned) and Yohel Pozo, who are expected to face charges. Both players are 19 years old.

MLB has placed the four players allegedly involved on administrative leave. In a statement, the Rangers said they were cooperating with MLB.
