Story highlights A man pleads guilty to terror and immigration offenses and receives six-year prison sentence

An invoice for ammunition worth $28.5 million was found on his phone, UK prosecutors say

Documents also showed the hiring of a cargo plane to be used in Libya, they say

London (CNN) A man received a six-year prison sentence Tuesday after admitting guilt to terror and immigration offenses, British prosecutors said. Police discovered images on his mobile phone showing an invoice for ammunition worth $28.5 million and the hiring of a cargo plane to be used in Libya.

Abdurraouf Eshati, 29, of Wrexham, Wales, was sentenced Tuesday at London's Old Bailey Court, the Crown Prosecution Service said.

"The information that was contained within those documents found on Eshati's phone were considered likely to have supported and been useful to an individual preparing to commit an act of terrorism," a Crown Prosecution Service representative said.

"Such was the scale of his activity, the court was told his arrest and the finding of these documents has led to Italian authorities discovering large-scale illegal arms supplies being imported from eastern Europe to conflict zones in Libya and other places."

The representative said, "The very fact that Eshati pleaded guilty to these offenses on the first day of his trial is a testament to the strength of the case and evidence brought against him."
