Shortly before 4 a.m., two suspects broke into a home in the 900 block of Haight Street occupied by four residents, according to police.
One of the suspects, who was armed with a handgun, woke up two of the victims in a bedroom. One of the victims was punched several times when he tried to detain that suspect, police said.
The suspects took a laptop and backpack from the home and fled in a vehicle described as a late 1980s or early 1990s four-door Honda or Toyota. They had not been found as of this morning, according to police.
The victim who was punched was taken to a hospital to be treated for cuts to his head. His injuries are not considered life-threatening.
