ALLENTOWN, Pa. -

A 22-year-old Allentown man has been arrested for the Dec. 16 armed robbery of Lafayette Ambassador Bank in Emmaus.

Emmaus police report Joshua Anthony Santos pointed what appeared to be a semi-automatic handgun at several bank employees during that robbery, in which he took $1,400.

Santos lives in an apartment in the 900 block of Walnut Street in Allentown.

Early Saturday morning, Allentown police responded to a disturbance outside the Holiday Inn at 904 Hamilton Mall in the city.

Shortly after 1 a.m., a Holiday Inn security officer observed Santos pacing back and forth outside the building, continuously looking in. The guard said Santos was wearing dark aviator sunglasses and a black hooded sweatshirt.

When the suspicious guard asked Santos to leave, the defendant pulled what appeared to be a handgun from his waist.  The guard wrestled Santos to the ground and was able to subdue him until city police arrived.

Police determined the weapon was a replica of a semi-automatic handgun, used for shooting airsoft pellets or BBs. They believe it is the same gun used in the bank robbery.

Police said Santos also was carrying a turquoise pillow case like the one used in the bank robbery.

Police went to Santos' home and showed his mother several photographs from the Dec. 16 bank robbery. She positively identified the male in the photos as her son.

During a search of Santos' bedroom, police found a black knit hat with a silver Oakland Raiders logo and a dark-colored hooded sweatshirt with a Champion logo on the front.

Both matched clothing worn by the bank robber, as did a pair of gloves.

Santos was charged with robbery and possessing instruments of crime by Emmaus police and committed to Lehigh County Prison.
