DETROIT (AP) _ Two teen-agers were arraigned Saturday on 11 felony charges each in a lunchtime shooting spree that wounded 11 teens-agers in a crowded restaurant, and a juvenile was being held, police said.

The eleven, who included one of the alleged attackers, were wounded Friday by gunfire or fragments when an argument between two groups of youths erupted into shooting in a McDonald's restaurant on Detroit's west side, police Deputy Chief Richard Dungy said.

One of the victims remained in serious condition Saturday.

The gunman opened fire with a sawed-off shotgun as students from Cody High School, a half-block away, ate their lunch, Dungy said.

He said the shooting apparently was sparked as students and non-students argued in the restaurant over damage to a car belonging to one of the teen- agers.

Jermaine Mosley, 14, said he was walking by the restaurant when he saw several people scuffling inside. Mosley said someone shouted '''Why did you shoot up my car?'' and then he heard shooting. After that, ''all of them just started scattering.''

Police picked up three people about an hour after the shooting, Dungy said, and later recovered a gun believed involved in the shooting.

Andre Duane Beard and Gregory Maurice Allen, both 17 and of Detroit, were charged Saturday with 10 counts each of aggravated assault with intent to commit murder, Lt. Fred Williams said. They also were charged with one count each of possession of a firearm during commission of a felony, he said.

Officials said Beard suffered pellet wounds in the leg. He was treated at Detroit Receiving Hospital and turned over to the police.

Beard and Allen, who Williams said police believe fired the shots, were arraigned Saturday before Magistrate Jimmylee Gray, who set bond for each at $100,000. Gray also set an Oct. 21 examination date.

Williams said police will ask a judge Tuesday to allow the third suspect, a 15-year-old juvenile, to be tried as an adult in the case. Williams said he was being held in lieu of $75,000 bond.

Three teen-agers remained hospitalized Saturday, said Mount Carmel Mercy Hospital spokeswoman Virginia Calihan. She said one was in serious but stable condition, one was in stable condition, and the third was in satisfactory condition.

Four victims were treated at Mount Carmel and released, and Oakwood Hospital spokesman Pat O'Dowd said three others were treated there and released.
