PHILADELPHIA (CBS) — Investigators say a third suspect has been arrested in connection with the random beating and robbery of a man and his brother inside a Northeast Philadelphia supermarket. A fourth suspect, a female, remains on the loose.

Investigators say 17-year-old Kevin Tavarez, 18-year-old Tomas Eanes, and 17-year-old Jose Ruiz have been arrested and are facing numerous charges.

The seemingly unprovoked attack happened at about 10 p.m. on September 29th inside the Pathmark on the grounds of the Franklin Mills Mall.

Police say one of the four suspects captured the attack on camera, and later posted the video on YouTube. The video has since been removed. But the damage has already been done.

The 47-year-old victim says he has to undergo reconstructive surgery after suffering an injury to his eye, nose and cheek. His brother says he too was also injured, taking a blow to the head.

Police say the suspects, who were caught on camera parking and entering the store, initially engaged in a verbal confrontation with the victim.

The altercation then escalated into a physical attack, during which the victim was punched, kicked and struck with a glass bottle.

One of the suspects then took the victim’s money clip, which contained $100 in cash. The suspects then ran out of the store and drove away.

Tavarez has been charged with Conspiracy, Robbery, Aggravated Assault, Possession of an Instrument of Crime, Receiving Stolen Property, Terroristic Threats, Theft, Simply Assault and Recklessly Endangering the Welfare of Another Person.

Eanes and Ruiz are facing charges of Conspiracy, Robbery, Aggravated Assault, Possession of an Instrument of Crime, Receiving Stolen Property, Theft, Simply Assault and Recklessly Endangering the Welfare of Another Person.

Both Tavarez and Ruiz have been charged as adults. All three defendants are scheduled to be arraigned later Thursday.

Police ask anyone with information on the remaining the suspect to call 911 or 215-686-TIPS (8477).
