New Orleans tourists attacked: 4 arrested in French Quarter beating

Two more men were arrested Wednesday -- for a total of four suspects in handcuffs -- after a violent robbery in New Orleans' French Quarter Saturday night left two tourists in the hospital, police said.

Rashaad Piper, 20, and Nicholas Polgowski, 18, were taken into custody early Wednesday morning, Fox 8 reported. Two other suspects -- DeJuan Paul, 21, and Joshua Simmons, 18 -- were also arrested earlier this week. Paul also faces drug charges after police discovered two bags of a powdery white substance in his packet when he turned himself in Monday night.

The four men were charged with second-degree robbery; however, the charges could be upgraded to homicide.

Two tourists, identified as James Curran and Tim Byrne, were visiting the city from Boston on Saturday when the four men ambushed them from behind. Curran and Byrne were attending the General Assembly of the Unitarian Universalist Association that weekend.
