The Department of State Services (DSS), yesterday, invited the Statistician-General of the Federation, Adeniran Adeyemi, for questioning following the release of a controversial survey report on ransom payments in Nigeria.
  
He was subsequently released by the secret police.  
  
The Guardian source revealed that the DSS was checking the methodology and data used in the report, which claimed that ransom payments had reached alarming levels, triggering widespread concerns.
  
According to the source, who wants to remain anonymous, “he was invited, but he was only asked few questions and allowed to go immediately.” A State House statement signed by Special Adviser to the President, Policy Communications, Daniel Bwala, had praised the Crime Experience and Security Perception Survey (CESPS), recently released by the National Bureau of Statistics (NBS), describing it as a novel concept that seeks to ensure that information rolled out to the public are data-driven, not on conjectures or mere assumptions.

Media reports also said Adeyemi was invited by the DSS to explain the methodology and data used in arriving at the report. This speculation was heightened when 24 hours after the release of the report, NBS raised the alarm that its website had been compromised.
