An Indianapolis police officer fatally shot a trespassing suspect who grabbed his gun Thursday evening, authorities said.

The officer and a partner had confronted the suspect inside a Burger King on the city's far east side just before 6 p.m. when a physical altercation ensued and all three fell to the ground, the Indianapolis Metropolitan Police Department said in a statement.
