Just as it emerged this week that the FBI cited the Trump dossier to obtain a surveillance warrant against Trump advisers, another allegation made in the 35-page document is coming under scrutiny.

A computer hacker identified in the dossier, compiled by former British spy Christopher Steele, is currently in a Russian prison on pedophilia charges, McClatchy reports.

And a Russian prison monitor who recently met with the man, Sevastyan Kaptsugovich, says that the prisoner does not have access to the Internet — a requirement for carrying out the cyber attacks alleged in the dossier. (RELATED: FBI Relied On Dossier To Obtain Warrant To Spy On Trump Adviser)

As McClatchy reports, Kaptsugovich, 45, is in prison in a small village in Russia’s Kirov region, 500 miles northeast of Moscow. He has been in and out of jail for pedophilia-related crimes since 2011. He was most recently sentenced to 18 years in a penal colony in 2013 for operating a network of child porn websites.

Kaptusgovich is identified in a Dec. 13 memo, Steele’s last report for the dossier, which was published by BuzzFeed on Jan. 10.

Steele compiled the memos on behalf of Fusion GPS, an opposition research firm working for an ally of Hillary Clinton’s.

The dossier refers to the alleged hacker as Seva Kapsugovich, a slight misspelling of his real name. McClatchy was able to verify that he is a computer expert and is currently in prison.

Artur Abashev, an official with the Public Monitoring Commission, a group that monitors Russian prisons, told McClatchy that Kaptsugovich is a prisoner at the penal colony and that he does not have access to the Internet, a computer, or a cell phone.

Abashev said that it is “unlikely” that Kaptsugovich would have been able to carry out the alleged cyber attacks given his lack of computer access.

The human rights worker confirmed his recent meeting in an email to The Daily Caller and said that Kaptsugovich is treated “negatively” by other prisoners because of the nature of his crimes. He also works in the prison bathhouse, washing bedclothes for other inmates.

Sources who talked to McClatchy did say that it is still possible that Kaptsugovich carried out the cyber attacks alleged in the dossier while at the penal colony. Russian intelligence services often recruit criminals and prisoners for computer hacking operations.

But other parts of the Dec. 13 memo naming Kaptusogovich have already been disputed.

The entry names the convict in the same paragraph as Aleksej Gubarev, a tech executive who is head of the web hosting companies, Webzilla and XBT Holdings.

In that paragraph, the dossier states that Gubarev’s companies and “affiliates had been using botnets and porn traffic to transmit viruses, plant bugs, steal data and conduct ‘altering operations’ against the Democratic Party leadership.”

The memo alleges that Gubarev and Kaptsugovich were recruited “under duress” by Russia’s spy services and were “were significant players” in the operation to hack Democrats.

But Gubarev strongly denies having been recruited by Russian spies or taking part in any cyber attacks. He is suing BuzzFeed News for publishing his name in the dossier. The website responded to the suit by apologizing to Gubarev and redacting his name from the online version of the document.

BuzzFeed also appears to have redacted Kaptsugovich’s name since its first publication of the dossier, though it is unclear why.
