Wichita officials say the city’s website was hacked during the weekend, potentially compromising the personal information of 29,000 vendors and employees.

The city said in a news release late Monday the hackers might have gained access to Social Security numbers, taxpayer identification numbers and banking information of vendors and former and current employees who were reimbursed for expenses since 1997.

The city says it has fixed the problem and is notifying those who might be affected.

City Manager Robert Layton says law enforcement agencies are investigating the incident.

The release said city officials are working with the state’s Enterprise Security Office to fix any remaining security concerns.
