Sheboygan, Wis. (WHBL) - Sheboygan Police are continuing their investigation into two separate armed robberies that occurred in the city Wednesday night.  Officers responded at about 9:30 to a report of a home invasion robbery in the Indian Meadows Mobile Home Park.  The residents said four black male suspects entered the home and demanded money.  They got a small amount of money and then fled on foot.  Then, just over an hour later, officers responded to a report of another armed robbery in the alley in the 1200 block of Pennsylvania Avenue.  An illegal drug deal was taking place at the time. During the deal, a male suspect, armed with a gun, took the victim’s money.  A 19 year old female and two males ages 23 and 26 are now in custody, and a handgun has been recovered that police believe was used in the robbery.
