A 64-year-old security guard told Columbus police a masked gunman robbed him this morning inside the Columbus Convention & Trade Center.
The guard said he was inside the 801 Front Avenue facility about 5:30 a.m. when a ski-masked man dressed all in black pointed a handgun at him and demanded his wallet and keys.
The guard said the gunman left him in an office, took $10 from his wallet, threw the billfold and keys down and left.
The guard told police the robber appeared to be in his 30s, but was unable to provide a more detailed description, investigators said.
