Police are investigating after the same Mobil gas station in North Long Beach was robbed twice within 24 hours.

It was unclear if the robberies were related, but police said they both happened this week at a gas station at Long Beach and Del Amo boulevards.

In both cases, a person armed with a gun came into the station, demanded cash from the clerks and then fled, Long Beach police spokeswoman Arantxa Chavarria said.

The first robbery was around 9:55 p.m. on Wednesday, and the second was at about 6:10 p.m. Thursday.

Authorities asked that anyone with information about the crimes contact detectives at 562-570-7464. Anonymous tips can be submitted through Los Angeles Regional Crime Stoppers at 1-800-222-TIPS or at lacrimestoppers.org.
