LAS VEGAS (AP) — A health-care protest at Sen. Dean Heller's Las Vegas office ended in five people being detained by authorities.

Las Vegas police Officer Larry Hadfield said the five people detained on Thursday were expected to be released with unspecified citations.

The Las Vegas Sun reports this is the second time this week that police have had to respond to Heller's office.

On Sunday, someone left a threatening note addressed to Heller that police found as they investigated a burglary alarm at the building.

Heller has been in the national spotlight as an on-the-fence Republican senator who could decide the fate of GOP efforts to repeal and replace Obamacare.
