A homeowner reported to authorities he’s received suspicious messages that he thinks were sent to persuade him not to testify against a former District housing official.

Todd Zirkle, who is renovating a home in the 1100 block of Fifth Street Northwest, told the FBI Monday he’s been approached by two men with similar stories who he believes were sent to persuade him drop his accusations against Yaw Agipong, a former head structural engineer for the D.C. Department of Consumer and Regulatory Affairs.
