MANSFIELD — Officials placed more than 50 people in protective custody, made several alcohol-related arrests and treated 46 people for alcohol-related illnesses during Saturday night’s Keith Urban concert at the Xfinity Center.

In a joint press release from the Mansfield police and fire departments released Sunday morning, officials said the country music concert swamped the venue with a higher-than-expected number of problems, prompting the need for mutual aid from Foxboro, Easton, Norton, Plainville and North Attleboro.
