Two “virtual kidnap” cases within 24 hours in this seaside community have led police to alert all local schools.

The incidents were similar: Phone calls were made to potential victims, with the caller demanding a large sum of money or threatening to harm a loved one.

“We definitely believe these incidents are connected,” said Sgt. Jim Cota, who last summer spearheaded assistance for a Laguna Niguel mother who sought help after receiving a threatening call.
