California police investigate after 27 fall ill at half-marathon running event

Police in Santa Barbara, California, are investigating after nearly 30 people had to seek medical care at a half-marathon running event held in the city on Sunday.

In a statement provided to the BBC's US partner CBS News, officers said they received a report from Santa Barbara Cottage Hospital about race participants who sought medical treatment "for unusual symptoms" after the race ended.

"The cause of the reported symptoms has not been confirmed," the statement added.

Cottage Health, which operates the hospital, told CBS it had seen "a larger than expected number of emergency visits" from those who ran the race.
