DETROIT -

Police didn't take any chances Monday after there were fears of retaliation, after a 19-year-old man was shot and killed during a Cinco de Mayo parade in southwest Detroit.

Police made a quick arrest Sunday, but that hasn't calmed fears in the area.

Mexicantown was rocking Monday night with one big fiesta, but just a few feet from the fun officers were heavily armed with cruisers on every corner. Plenty of police were driving, riding and walking around checking out the crowd.

Police feared there would be retaliation after Sunday's shooting at the Cinco de Mayo parade.

Family members of 19-year-old Andres Dejesus said he was taking up for a relative when he was shot and killed.

Police were not taking any chances at the celebration Monday night. Officers from the gang intelligence and high crime units were out in full force.
