Four people’s lives were saved from a Boston fire that broke out late Tuesday afternoon by a good Samaritan, ABC Boston reported.

The stranger, a man named Rene Lucas, explained to ABC that he was driving when he spotted flames off of Cumin Highway. He and his friend didn’t think twice before pulling over to help.

"We didn't think twice," Lucas explained. "We just parked the car and boom went inside the house and just started knocking on windows and doors. We said, 'The house is on fire, everybody out, everybody out.'"

The residents he warned all poured praise on the man who did a good deed.
