The Los Angeles Police Department said Monday it has opened a criminal investigation into New York Knicks player Derrick Rose over rape allegations against him. An LAPD detective confirmed the existence of a probe in a letter to lawyers for Rose’s accuser, who wants to remain anonymous. Rose could miss the beginning of the season if the lawsuit is not settled before the trial date of Oct. 4. “He’s aware of it, but it’s not keeping him up at night,” Knicks President Phil Jackson said. The case is a civil suit seeking $21.5 million.
