SAN CARLOS, Calif. (KRON) — A man was taken into custody after allegedly assaulting a man before barricading himself inside of a residence early Saturday morning, according to a release from the San Mateo County Sheriff’s Office.

Just after 6 a.m., San Mateo County Sheriff’s Office deputies responded to a report of an assault near the 300 block of Dartmouth Avenue. The Sheriff’s Office Crisis Intervention Trained deputies arrived at the scene and found a man who was being treated by fire and emergency medical crews due to a large laceration on his head.
