Police activity has shut down a street in San Leandro this morning.
Officers have closed Elsie Avenue as they search for a man who is on foot and may have a gun, police Lt. Randall Brandt said.
Several officers saw a man traveling at a high rate of speed nearing 100 miles per hour at about 7:15 a.m., Brandt said.
The man, believed to be white or Hispanic and in his 20s, turned onto Elsie then crashed into the front of a home, Brandt said.
Brandt said the man, who was wearing a blue sweatshirt and jeans, fled the car with a backpack.
Some residents told police they saw the man with a gun, Brandt said.
San Leandro Police units set up a perimeter and checked the area for the suspect but were unable locate him.
