ACC Secretary Dilwar Bakht said this to the reporters at the anticorruption watchdog's office on Monday.
Earlier, Foreign Minister AK Abdul Momen talked about the capital flight from Bangladesh to Toronto's Begum Para.
Dilwar said, "We are investigating the issue of 28 houses owned by government officials in Begum Para and have asked the government for a list."
"We will start working on it when the list is available."
On November 18, the foreign minister talked about 28 money laundering cases in this connection at a program of the Dhaka Reporters' Unity.
"I thought the number of politicians would be higher, but there were only four of them and a few businessmen. The majority was government officials."
