Times editor James Harding has been recalled to appear at the Leveson inquiry into press ethics following claims the paper engaged in email hacking.
Last month Harding told Leveson that one of his reporters - later named as Patrick Foster - had admitted hacking into an email account and was given a formal warning.
In 2009 The Times named Lancashire detective Richard Horton as the author of the award-winning NightJack blog in June 2009 after the High Court refused to grant him anonymity.
According to the BBC Harding is o make his second appearance at the inquiry on Tuesday where he is expected to be questioned about the extent to which he knew about the incident at the time.
On Thursday morning Labour MP Tom Watson claimed that the broadsheet was being investigated by police.
In a letter sent to the Met last month, Watson urged officers to examine whether a crime had been committed and whether the newspaper had misled the court.
"In an attempt to protect his privacy, the police officer in question sought an injunction," the MP wrote. "Far from putting forward a public interest defence, lawyers representing The Times claimed that the information was obtained through entirely legitimate means...
"It is clear that a crime has been committed - illicit hacking of personal emails. It is almost certain that a judge was misled."
The Metropolitan Police said: "We can confirm that a letter was received on Monday 23 January from Tom Watson. Officers from Operation Tuleta are in contact with Watson in relation to the specific issues he raised. We are not prepared to give a running commentary on the investigation."
