Five more Omaha city workers have been suspended after testing positive for illegal drugs.
Omaha station KETV reports that now a group of 16 including some who drive snowplows, dump trucks and other heavy equipment - are suspended with pay. The group includes one foreman, a supervisor who previously failed a drug test.
Fifteen other workers had their drug tests come back inconclusive. Some 425-city employees holding commercial driver's licenses were tested last week. The original eleven were suspended Tuesday.
The tests could detect illegal drugs like methamphetamine and marijuana. City officials declined to say which drugs were found.
City Councilman Marc Kraft said he now wants city workers tested more frequently. He also told KETV that he wants changes in how the city deals with those who fail the test.
