A man was arrested early Monday after Charleston police officers said he threatened to shoot a homeless man with one of the suspect's dozen firearms, then took the homeless man's bicycle.

Stephen Matthew Miernicki, 33, faces a charge of larceny of a bicycle and simple assault in connection with the incident near his apartment, at 286 Meeting St.

According to a report from the Charleston Police Department, the homeless man offered to help Miernicki get home because the man thought Miernicki was intoxicated.

But close to the apartment building, Miernicki became irate with the man and "threatened to harm him with a gun," according to the report.

Just after midnight, the man dropped his bicycle, walked away and flagged down police officers. In Miernicki's apartment, the officers said they found the $50 bicycle, along with 12 firearms, including three AK-47s and four .308-caliber military-style rifles.

Police valued the collection at $5,300.

Police spokesman Charles Francis said all the firearms were legally owned, they were taken for safekeeping, and they will be returned.
