A security guard posted inside a high-end jewelry store in Chicago foiled a broad daylight smash-and-grab on Tuesday, authorities said.

The attempted heist happened just before 12:30 p.m. at the Marshall Pierce & Company jewelry store in the 900 block of North Michigan Avenue in the city’s Magnificent Mile neighborhood, Chicago police said.

Before the suspect could smash any glass cases, police said a security guard intervened and ordered the suspects to the ground. The three suspects refused to listen to the guard, who was reportedly armed, and fled the store empty-handed.

The trio jumped into a waiting getaway car, which police believed may be a white Infiniti sedan.

The suspects were wearing ski masks and described as slim Black males between the ages of 18 and 28, CWB Chicago reported, citing police.
