The San Diego County district attorney office says 33 people have been arrested and charged with selling drugs at military housing.

Authorities said Tuesday that the three-month investigation resulted in seizures of two pounds of methamphetamine, a half-pound of cocaine, six pounds of marijuana and seven guns.

Deputy District Attorney Chris Lindberg says two sailors and one person who recently left the Navy were charged. The rest are civilians.

Authorities declined to pinpoint where the alleged sales occurred but said they were in San Diego neighborhoods with mostly Navy housing.

Most suspects were arrested in late January and early February. Most face between 16 months and five years in prison if convicted.
