UCLA on Tuesday night said Los Angeles police used its Jackie Robinson Stadium, named for Major League Baseball's first African American player, to temporarily house people who had been detained.

"We’re troubled by accounts of Jackie Robinson stadium being used as a 'field jail,'" the university said on Twitter. "This was done without UCLA’s knowledge or permission. As lessee of the stadium, we informed local agencies that UCLA will NOT grant permission should there be a request like this in the future."

The Los Angeles Police Department acknowledged using the field in West L.A. for suspects arrested during the city's George Floyd protests. "We are no longer using it," Officer Mike Lopez said.

The field, home of the men's UCLA baseball team, is leased and occupies federal Veterans Affairs land. It's not clear what exactly the lease allows or disallows the city to do. The V.A. land is on an island of unincorporated Los Angeles County that is not in the city's jurisdiction.
