A driver authorities thought was armed after he ran from the scene of a car crash about 10:30 a.m. on westbound Interstate 8 near Alvarado Hospital was captured about a half hour later, police said.
The man fled the crash scene, crossed the freeway and was seen near the hospital, said San Diego police Officer Travis Easter.
San Diego State University police issued campus alerts throughout the search for the potentially armed man because the hospital is near the college. The campus was put on lockdown, and police told people to shelter in place. Doors were locked to classrooms during the shelter-in-place order.
About 11 a.m., police said the man had been captured and the lockdown was lifted.
