The official in charge of all New Orleans building inspectors was one of two city employees suspended last week amid a broad federal probe of corruption allegations in his department, according to city records.

Larry Chan, who holds the title of "building official" and is in charge of inspecting and approving construction projects, was put on emergency suspension last week via a letter to him from Chief Administrative Officer Gilbert Montaño. The suspension was “based on an ongoing investigation into your involvement in the alleged illegal issuance of city permits," the letter said.

Montaño also suspended Richella Maxwell, a business development specialist in the Department of Safety and Permits, for the same reason, according to city records.

Both Chan and Maxwell, longtime city employees, will be suspended for up to 120 days while an internal investigation proceeds, according to the notices.

Mayor LaToya Cantrell’s administration confirmed the suspensions last week but refused at the time to name the employees or their job titles.

A spokesman said Tuesday that no other employees have been suspended, but declined to comment further on the suspensions.

Chan, who has worked for the city since 1987, could not be reached on Tuesday.

Maxwell, who was originally hired in 1997, did not respond to messages seeking comment. Maxwell’s job title covers an expansive range of administrative services within city government and it was not immediately clear what her exact duties have been.

The suspensions came a month after U.S. Attorney Peter Strasser’s office indicted Kevin Richardson, a former city building inspector, for allegedly seeking and accepting bribes to OK buildings that had not been inspected or were not up to code.

In addition to taking bribes from building owners, Richardson was also accused of bribing a permit analyst in the department to issue permits without the proper reviews. The federal indictment doesn’t name the permit analyst or any of the other people involved in the alleged wrongdoing.

Richardson was fired in 2015, under former Mayor Mitch Landrieu’s administration, after being put on his own 120-day emergency suspension.

Richardson pleaded not guilty to the bribery count last month and remains free without bail, though his attorney said last week that his client plans to plead guilty to the charge against him.

Sources have also confirmed that federal law enforcement is taking a wide-ranging look at alleged corruption in the department, and that the probe is expected to yield additional indictments. It's not clear if the investigation is targeting primarily city employees or developers who do business with the city.

The exact nature of the allegations against Chan and Maxwell, and whether they are directly tied into Richardson’s indictment, has not been made public. But John Hill Thomas, Richardson’s attorney, said last week that the complex case had been building for years. He said “numerous other people” were involved.

The investigation has involved the inspectors general of the city, the U.S. Department of Housing and Urban Development and the U.S. Department of Homeland Security, in addition to the U.S. Attorney’s Office.
