UTSA police say the suspects involved a standoff Tuesday afternoon fled the scene and remain at-large.
Officers received a report of an assault and robbery around 2 p.m. at The Outpost Complex in the 6800 block of UTSA Boulevard.
A man said he was robbed by two men who fled into an apartment, and at least one suspect was carrying a rifle.
SWAT officers were called and attempted to negotiate with two men believed to be in the apartment, but found no one inside.
Police do not believe the suspects live at the complex. Anyone with information is asked to call police.
