Sen. Patrick Brazeau underwent emergency surgery early Tuesday morning after police found him seriously injured at his Outouais home, the Hull hospital confirmed.

The undisclosed surgery was successful and the 41-year-old senator is in critical, but stable condition, a statement released by hospital spokeswoman Genevieve Cote Tuesday.

Brazeau was admitted to the hospital at around 1 a.m. and underwent a successful operation, the hospital said. The hospital didn’t specify what kind of surgery he had.

Quebec provincial police and paramedics were called to Brazeau’s home just after 10 p.m. Monday to Brazeau’s home. He was seriously injured when they found him and he was taken to hospital for treatment.

Police aren’t saying exactly what happened, but did say that the incident was not criminal or that any criminal activity was involved.

Brazeau’s lawyer tried to see his client Tuesday morning after learning he had been hospitalized but wasn’t able to make contact.

“I went to the hospital and I could not get to him,” said Christian Deslauriers, an Ottawa lawyer who is representing Brazeau on charges he defrauded the Senate over living expenses he filed.

Brazeau went public last summer about a suicide attempt, saying it was caused by the decisions then-prime minister Stephen Harper made to have the Senate suspend him over the fraud charges and other legal problems.

Brazeau reported the suicide attempt on his Twitter account in August 2015, though he never specified when the incident took place.

Deslauriers said he could not offer any information about what led to Brazeau’s hospitalization Monday night or whether it was another attempt to end his life.

“That’s what I hear in the media. But I cannot confirm. I cannot reach anyone from the family right now, so it’s difficult,” he said.

Deslauriers said he had been scheduled to meet with Brazeau today to prepare for the upcoming fraud trial.

“I don’t know what’s going to happen now.”

The hospital asked for privacy for Brazeau’s family, which didn’t offer any public comment on the incident.
