The ban will be in effect for six months, and some bars will be required to close by 1 a.m. for the next month, according to a statement from the mayor’s office.

The mayor of Medellín, the second-largest city in Colombia, announced Monday a temporary ban on prostitution in two of its neighborhoods, days after an American tourist was discovered in a hotel room with two underage girls, according to The Associated Press.

Mayor Federico Gutiérrez said the ban would affect Provenza and El Poblado, popular destinations for international tourists and local sex workers, and he cited concerns about sex trafficking involving minors.

The ban will be in place for six months, and bars in Lleras Park will be required to close by no later than 1 a.m. over the month of April, according to a statement from the mayor’s office released Monday.
