SOUTH PHILADELPHIA (WPVI) -- Philadelphia police need your help finding two robbery suspects accused of carrying out a violent jewel heist.
Cameras captured the men pretending to shop at H and Y Royal Jewelers on South 23rd Street, Monday evening.
At one point, the video shows one of the suspects actually adjust a fake sleeve of tattoos as he points out an item.
After a few minutes, the men persuade the 53-year-old clerk to come out from behind the counter.
That's when one of the thieves punches the clerk, knocking him straight out his shoes.
He then ties the clerk up, holding him at knifepoint.
Meanwhile, the other suspect ransacks the safe and shelves, stealing a large amount of jewelry.
The worker was able to free himself and activate the alarm after the thieves fled.
Anyone with information is urged to contact police.
