10-year-old boy allegedly stabs 7-year-old with kitchen knife: Mountain View police

A Mountain View police car is in front of Bubb Elementary after a 10-year-old stabbing suspect taken into custody. 

A 10-year-old boy was taken into custody after Mountain View police said he stabbed a 7-year-old with a kitchen knife at Bubb Elementary School while the child was in the school's play area.

What we know:

The stabbing occurred Wednesday at approximately 3:30 p.m. during an after-school program at the school, police said. 

The 7-year-old was treated at the scene by Mountain View firefighters and released to a parent, police said. 

Authorities recovered a kitchen knife at the scene, which police say they believe was the stabbing tool.

What we don't know:

It's not clear what the relationship between the two children was, or the motive for the stabbing. But police did say the boy had no connection to the school or the after-school program.

After the stabbing, the boy ran away, police said. 

But he was later located by an officer, who reviewed some nearby home surveillance video and recognized him since he had "prior contacts" with police. 

Those contacts were not explained. 

A Los Altos Police Department K-9 unit helped find the boy from the school to his home. 

Officers coordinated with a guardian and took the boy in, police said. 

The boy was subsequently transferred to Pacific Clinics, which is Santa Clara County's juvenile mental health services.

Since they are juveniles, police will not release much more information about the stabbing.
