Nassau's Major Case Bureau is investigating two armed robberies that happened in less than 12 hours from each other.
The first robbery was at a 7-Eleven on Oak Street in Uniondale at 4 a.m. Thursday.
About nine hours later in Westbury, a man armed with gun walked into the Dunkin on Old Country Road and demanded money.
News 12 is told the incidents are not believed to be connected.
No one was injured, but the thieves both stole cash from the stores.
