Sports fans, college graduates and others can expect heightened security at U.S. arenas after Monday night’s bomb attack in Manchester, England that killed 22 and injured 59, the Wall Street Journal reports. Officials at Quicken Loans Arena in Cleveland had “additional appropriate” security measures for last night’s NBA playoff game between the Cleveland Cavaliers and Boston Celtics. The officials declined to elaborate. The series is in Boston’s TD Garden arena tomorrow, and fans are being asked to arrive early because of increased security. College administrators and security personnel are also taking additional precautions ahead of graduation activities that will bring thousands of visitors to campuses or nearby arenas.
Police in several cities stepped up patrols, including in New York, where police rolled out counterterrorism units to music venues, transit hubs, sports arenas and other locations, as the England attack renewed concerns about the vulnerability of public gatherings. The Boston Police Department said it has increased patrols at concert venues as a precautionary measure. There was greater security presence outside Oriole Park at Camden Yards before and after last night’s game Baltimore Orioles-Minnesota Twins game. “Everything inside of the stadium walls we feel very good about,” he said. “It’s the exterior [where] we have to be vigilant.” The suicide bombing outside a pop concert in Manchester highlighted the challenge of guarding against such an attack near a facility’s exits, said Mitch Silber, the New York Police Department’s former director of intelligence analysis. “That’s a much more nefarious and harder to detect phenomenon,” said Silber, a security risk consultant for FTI Consulting. “Some type of adjustments are going to have to be made in the way the perimeter of stadiums are covered as events come to a close.”
