Reports from Pakistan indicate that eight of the 10 men reportedly jailed for the attempted assassination of Pakistani schoolgirl, Malala Yousafzai, were set free.
In April, officials in Pakistan said that 10 Taliban fighters had been found guilty and received 25-year sentences.
The BBC reports that only two of the men who stood trial were convicted.
The secrecy surrounding the trial, which was held behind closed doors, raised suspicions over its validity.
A spokesman for the Pakistani High Commission in London, Muneer Ahmed, says the eight men were acquitted because of a lack of evidence.
Meanwhile, Saleem Marwat, the district Police Chief in Swat, Pakistan separately confirmed that only two men had been convicted.
Mr Ahmed claimed that the original court judgement made it clear that only two men had been convicted, blaming the confusion on misreporting.
