(KJRH) Police in Tulsa, Oklahoma say armed robbers stapled a man's lips during a home invasion early Monday.
Officers say three men armed with shotguns broke into an apartment around 1 a.m. and demanded money and drugs.
Three adults and a toddler were in the apartment at the time.
Investigators believe the men stapled one victim's lips with a carpet staple gun as a warning against cooperating with police.
