FT LAUDERDALE (CBSMiami) – Hoping that a little more ‘green’ will get someone to pick up the phone, the reward for information which leads to arrests in a string of Broward armed robberies is going up.

Crime Stoppers says the Bureau of Alcohol, Tobacco and Firearms is kicking in $12,500 and Family Dollar is adding $2,500 which brings the total reward to $15,500.

Surveillance video shows a couple of guys creeping up to the entrance of the Family Dollar store at 68th and Taft in Hollywood.  They were there to rob the place.

The video also shows, possibly same pair, rushing into a 7Eleven next door and jumping the counter.

Just down the street, they’re also suspected of hitting an adult book store.  “I was kind of traumatized, I’m telling you,” said clerk Rene Galdamez.

Galdamez was working a the Sensation Adult video when two men with guns came in, ordered him and another man to the bathroom, and then tied their hands with computer cord.

“They tie it like that,” he demonstrates by putting his hands behind his back.  “(They) put us in the bathroom, close the door, put a chair try to lock the door and the left.”

Galdamez could not see their faces, no one has.

Investigators said each time the guys are wearing hoodies and their faces are concealed.

In surveillance video from the Hollywood Family Dollar store, one is wearing a surgical mask and their hands are always covered with gloves.

“We’ve determinted that these indviduals are very organized and have put some planning into the robberies,” said Hollywood Police Lt. Derik Alexander.

Hollywood Police are leading the investigation.

They’ve hit at least 5 times in Hollywood and several more times nearby.  Even kids were bound during their robberies.  That tells police these guys are rough.

“They didn’t have any hesitation whatsoever in treating the juvenile victims in those instances the same as they did the adults,” said Lt. Alexander.
