An Indiana town is requiring gas stations to close overnight in response to an uptick in violent crime across the city.

City leaders in Hammond, 25 miles south of Chicago, voted 7-2 Monday in favor of requiring the gas stations to close between midnight and 5 a.m., FOX Chicago reported. 

The measure will impact 37 gas stations. City leaders said violent crime – often involving firearms – have occurred at gas stations late at night and in the early morning hours over the last several years.

Hammond Mayor Thomas McDermott voiced his support of the ordinance after a murder that occurred at a gas station after 2 a.m. in July. 

"A lot of the crime taking place in our city happens after hours at gas stations. We've talked about this for a number of years," he said at the time. "It was time to put my foot down and say this is enough."
