The hip-hop world has been hit with sad news once again, this time in England. On Wednesday (Aug. 2), U.K. drill rapper, Incognito, was stabbed to death in the Camberwell district of south London. He was 23 years old.

Incognito, whose real name is Siddique Kamara, was a well-known rhymer in London's underground rap scene and belonged to the group Moscow17, The Independent reports. “Today we have taken a very sad loss in our member @SK017_ /Incognito , we ask for all prayers be directed towards him & his family," a tweet from the group's Twitter account reads. Tragically, just a few days before his death, Kamara wrote of devastation in his neighborhood. "My Part Of My Hood Is Tragic Right Now ... I Walk With Allah Daily I’m Blessed," he said on July 30.

Incognito reportedly died on the same road as another member of Moscow 17, a 17-year-old by the name of Rhyhiem Ainsworth Barton, who was shot earlier this summer in May.

Police are now reportedly launching a murder investigation and are treating the stabbing as a "gang-related" incident. They are urging any individuals with information to come forward. Along with Kamara, two other men, ages 16 and 31, were found with non-life threatening injuries. Two male suspects, ages 18 and 19, remain in custody after they were arrested close to the crime scene.

“Another young man has tragically and needlessly lost his life through an act of violence," reads a statement from Detective Chief Inspector Richard Leonard. “We are keeping an open mind about the positive motive for this attack, but at this early stage one line of enquiry is this being gang-related." Even the Mayor of London, Sadiq Khan, issued a statement on Twitter about Kamara's passing. “My heart goes out to the family of the 23-year-old man fatally stabbed last night in Southwark," he wrote.

Drill rap in the U.K. has come under fire as of late, as police attempt to get the music videos banned from YouTube. In May, the video-hosting network removed up to 30 videos from its site after authorities claimed gangs are using the videos to threaten each other.

The following month, London police attempted to ban drill group 1011 from making music, claiming their videos are "clearly and only designed to incite violence." The group fired back with a petition, calling for police to stop targeting them.
