Chinese police were called to UCLA’s team hotel in Hangzhou, China, on Tuesday to investigate an unknown matter, according to the Atlanta Journal-Constitution.

Both the UCLA and Georgia Tech men’s basketball teams were staying at the Hyatt Regency Hangzhou in preparation for their season-opening game this weekend. According to the Atlanta Journal-Constitution, local police searched the UCLA team bus’ cargo compartment and questioned three Georgia Tech players who were later cleared. UCLA players who were waiting to go to practice on the bus had to leave after a delay and return to the hotel.
