A Fairfax County land-use official who bought and sold several properties while working in the county's Office of Comprehensive Planning did not profit from using inside information and has been cleared of any wrongdoing, county officials said.

Ahmad Malek-Mohamadi, who heads the county's General Planning Information Office, and his wife, a part-time real estate agent, did not profit from information he had about rezonings and other potential land-use changes, according to Richard A. King, deputy county executive for public safety. Police began their investigation in February after a resident complained that Malek-Mohamadi had used his position to discourage someone from buying land that he wanted.

King said Commonwealth's Attorney Robert F. Horan Jr. reviewed the police findings and concluded there had been no violation of state or county laws.

County land records show that Malek-Mohamadi or his wife has been involved in at least 13 property transactions in Fairfax since 1983. "There is absolutely no evidence that he committed any crime," Horan said. He said that Malek-Mohamadi purchased the properties at market value and properly disclosed the transactions.

Horan said Malek-Mohamadi "didn't have a position in the chain of command where he was deciding how county land was planned or zoned" and that much of his property was purchased before he got involved in the county planning process.
