A duo arrested Saturday morning for their alleged involvement in robbing and beating a cab driver appeared in court Sunday.

Anchorage Police say 21-year-old Shirley Borrero-Qinones and 20-year-old Hector Rivera were found in an apartment in the area of 15th and Cordova streets around 8 o'clock Saturday morning, largely in part due to a tip through Crime Stoppers.

APD said the apparent crime happened in March.

When the cab driver pulled over for the group, a police report indicates that he was robbed and beaten by two individuals, with a third individual nearby. The cab driver alleged the suspects fled the scene in a dark sedan.

According to charging documents, an iPhone, wallet and $400 were taken from the victim. The cab driver told police fraudulent charges were made with his debit cards at two different gas stations after the assault. "Follow-up with the two Chevron Stations revealed that $19.56 worth of gas was purchased at 2500 Seward Highway about eight minutes after the robbery was reported."

Court papers claim two additional purchases for $63.32 and $16.39 were made less than seven minutes later.

Rivera and Borrero-Qinones could face a maximum sentence of 20 years behind bars for the most serious offense if convicted of the crime.

Borrero-Qinones is being held in lieu of a $10,000 appearance bond. Rivera is held in lieu of a $50,000 appearance bond plus a $50,000 cash performance bond. A judge ordered both to be held on house arrest with a mobile ankle monitor with GPS tracking as a condition of release.
