The operatives had been instructed from the office of the commission’s chairman to mark such houses.
The operatives are focusing attention on properties in Lagos, Abuja, Yenagoa and Port Harcourt.
“It would not be correct to conclude that the commission has halted the investigation into the activities of the former First Lady,” a source told Punch.
“The investigation is progressing and it is being handled by the office of the chairman of the commission.
“A team of operatives has been assembled to identify all her properties in the country with a focus on Abuja, Port Harcourt and Yenagoa.
“The responsibility of the team is to mark all such properties in preparation for a possible court action.”
Meanwhile Justice Babs Kuewumi of a National Federal High Court in Lagos has fixed December 7 to hear a suit filed by Mrs. Jonathan seeking to un-freeze her account.
EFCC had traced $5m to the personal account of the former First Lady. It froze the account domiciled in Skye Bank Plc last month.
Mrs. Jonathan’s troubles started when the commission froze the accounts of four companies traced to the Special Adviser to ex-President Jonathan on Domestic Affairs, Waripamowei Dudafa.
The four firms identified as Pluto Property and Investment Company Limited; Seagate Property Development and Investment Company Limited; Trans Ocean Property and Investment Company had a total of $15,591,700 in their accounts.
