Police release surveillance images of Mother's Day shooting (Third Lead)

Police have released video surveillance of a suspect wanted in the Mother's Day parade shooting in New Orleans, the largest city in Indian American Governor Bobby Jindal's state of Louisiana, injuring at least 19 people.

The footage shows still images taken from the scene of the parade minutes before and after the shooting, including footage of one of the three suspects involved, according to local Nola.com.

The grainy surveillance video shows a crowd suddenly scattering in all directions, with some falling to the ground, according to CBS

They appear to be running from a man who turns and runs out of the picture. The man is wearing a white T-shirt and dark pants. The image isn't clear but police say they hope someone will recognize him and notify investigators.

Still pictures of the suspect have been posted on YouTube, police said.

Mobile phone video taken in the aftermath of the shooting shows victims lying on the ground, blood on the pavement and others bending over to comfort them, CBS said.

Crimestoppers, a national crime stoppers organization spread across US, has doubled its standard $2,500 reward to $5,000 for information about the crime.

In addition, the federal Alcohol, Tobacco and Firearms Bureau has added $5,000 to that reward, bringing the total to $10,000, Nola.com said.

No fatalities have been reported so from the Sunday afternoon's shooting, which is the fourth major incident of mass shootings in a year in the US, where gun culture is endemic and a powerful gun lobby has prevented passage of stricter gun laws.

The wounded in the shooting in the city, known as the home of jazz, included 10 men and seven women as well as a boy and a girl, both 10, with graze wounds to the body.

The victims were marching in what is known as a second line parade, or a crowd of revellers following the traditional "main line" or "first line" brass band marching in the streets.

New Orleans Police Superintendent Ronal Serpas said there may have been as many as three shooters and that two different types of weapons were likely used.

There were about 300 to 400 people participating in the Mother's Day parade and about 200 people were apparently in the area at the time of shooting, Serpas said.
