According to recent reports, the man convicted of assassinating Robert F. Kennedy, has been stabbed at a California prison.

Authorities said a stabbing happened at a prison near San Diego on August 30.

In a statement, the California Department of Corrections and Rehabilitation said “officers responded quickly” to the attack.

The victim, whose condition is stable, was not named in the statement.

However, citing unnamed law enforcement sources, multiple media reports have identified 75-year-old Sirhan Sirhan as the victim.

Sirhan Sirhan is serving a life sentence at the Richard J. Donovan Correctional Facility, where the stabbing took place.

According to TMZ, which first reported the assault, the suspected attacker, a fellow inmate, has been placed in isolation.

The motive for the attack, which is under investigation, has not been revealed by officials.

Sirhan Sirhan was convicted of murdering presidential hopeful Robert F. Kennedy, who he shot three times at the Ambassador Hotel in Los Angeles on June 5, 1968.

Robert F. Kennedy was shot in the kitchen of the hotel, shortly after declaring victory in California’s Democratic presidential primary to cheering crowds.

The New York senator, brother of former Democratic president John F. Kennedy, died in hospital 24 hours later.

Robert F. Kennedy was later buried at Arlington Cemetery, near his brother John, who was assassinated in 1963.

At his trial in 1969, Sirhan Sirhan was originally sentenced to death. Three years later, however, his sentence was commuted to life in prison when California briefly outlawed capital punishment.

A Palestinian with Jordanian citizenship, Sirhan Sirhan has claimed he has no recollection of shooting Robert F. Kennedy.

In a TV interview, Sirhan Sirhan said he felt betrayed by Robert F. Kennedy’s support for Israel in the 1967 Six-Day War.
