CARMEL, Ind. (AP) _ A man walked into a bank, demanded money and started shooting today, killing one person and wounding three others. The robbery was followed by a second attempt a few miles away, and a suspect was wounded and arrested.

The fatal robbery occurred at a Key Bank in this suburb north of Indianapolis. At least one suspect fled the scene with an undisclosed amount of money.

Carmel police received a 911 call at 9:06 a.m.

``A lone holdup man came into the bank, demanded money and for whatever reason started shooting,'' said Janet Uhrick, a spokeswoman for Carmel Police.

All four employees, the only people present in the bank, were shot. One of the three wounded was in critical condition.

A short time later, police responded to an attempted robbery at a People's Bank in Indianapolis, seven or eight miles south of the Carmel bank. A man fled in a stolen car and was wounded when officers shot out the windows. He then attempted to run away but was apprehended about 10 a.m. as news helicopters photographed the scene. His condition wasn't immediately known.

``There was a lengthy chase. At one point he started shooting at the officer who was coming after him,'' said Detective Dennis McAtee of the Marion County Sheriff's Department.

A witness to the first robbery, Ron Prater, told police he was in a nearby auto license branch at the time.

``Somebody ran in and said there's been a bank robbery and people, shot so I went outside to see if I could be of any assistance,'' Prater said. ``I did not see who left the bank or anything, but I did see a man in the parking lot that had been shot. So I ran out and assisted him inside the license branch.

``He was going into shock because of what happened. ... I made a tourniquet out of his necktie.''

Police ordered all Carmel schools be locked. Carmel Junior High School is near the bank.

One woman was shot in the neck and hand and was listed in critical condition. A 21-year-old woman who was shot in the shoulder and a 44-year-old man who was shot in the arm were listed in fair condition, according to Methodist Hospital spokeswoman Jennifer Farley. All were believed to be employees of the bank.

No information was immediately available about the dead person.

McAtee said it was unclear whether the man apprehended after the second robbery was the same man who opened fire at the Carmel bank.

``It could turn out that it's just two guys who decided to try to rob banks in that part of town on the same day,'' he said.
