Boston police arrested one man and dispersed unruly fans on Lansdowne Street Wednesday night after Kodak Black failed to show up for a performance at the House of Blues because he was arrested on the Canadian border in New York.

Unbeknownst to his fans, the Florida rapper, whose legal name is Bill K. Kapri, missed the concert because he was detained by US Customs and Border Protection after a weapon and drugs were found in the vehicle he was driving, officials said. Kapri was arrested and charged with unlawful possession of marijuana and criminal possession of a weapon, officials said.

Boston police are also investigating a sexual assault that took place inside the crowded House of Blues nightclub, police wrote in a posting on bpdnews.com. Details of the incident were not released because of the ongoing investigation.

Officers responded around 8:20 p.m. to investigate the sexual assault. When they arrived, they found a crowd of concert-goers “displaying generally unruly behavior” as a result of the canceled show, according to Officer Stephen McNulty, a department spokesman.

McNulty said there were approximately 200 people outside and 800 people inside the club at the time.

Additional officers were called in and it took police about 30 minutes to clear the scene, he said.

McNulty said police arrested one man who allegedly assaulted a member of the security staff. The man, identified by police as Samuel Simmons, 20, of Newton, allegedly tried to get back in the club through an emergency exit.

Simmons was charged with assault and battery, disorderly conduct, and trespassing , police said.

He is due to be arraigned May 1 in Roxbury Municipal Court, according to the Suffolk district attorney’s office.

The House of Blues will be issued a licensed premises violation for the sexual assault and the altercation allegedly involving Simmons and a nightclub staff member.

Earlier that evening, while fans of Kodak Black were gearing up for his Boston show, the rap artist and his entourage found themselves in trouble with the law at the Canadian border. New York State Police reported that at approximately 7:20 p.m. troopers from Niagara Falls were dispatched to the Lewiston-Queenston Bridge where Kapri and several other men were being detained by US Customs and Border Protection.

New York State Police said Kapri was driving a Cadillac Escalade bearing a temporary California registration with two other men when they tried to cross into the United States. Authorities reported that Kapri had marijuana and a Glock 9mm pistol was found in the vehicle.

Three men in a Porsche were also traveling with the Cadillac. The driver of the Porsche “declared having two loaded handguns and a third was found in the trunk during an inspection along with marijuana,” New York State Police said in a statement.

Kapri and his entourage were subsequently placed under arrest.

“During the initial inspection, the US citizens admitted to being in possession of marijuana and firearms,” US Customs and Border Protection officials said in a statement. “During a secondary inspection, it was revealed that the weapons were possessed unlawfully in New York State and subsequently the marijuana, firearms and subjects were turned over to the New York State Police for further processing.”

Kapri, 21, of Miramar, Fla., and Jeantony Saintmelus, 22, of Lauderhill, Fla, were charged with criminal possession of a weapon third degree and unlawful possession of marijuana.

Stetson J. President, 24, of Pompano Beach, Fla., and Madarrow D. Smith 20, of Lauderhill, Fla., were both charged with criminal possession of a weapon third degree (C Felony), police said.

The suspects were arraigned in the town of Lewiston Court and remanded to Niagara County Jail and are due to return to Lewiston Court in May, police said.

Kapri’s attorney, Beattie B. Ashmore, declined to comment.
