A Nigerian driver killed four people in anger at the defeat of Manchester United soccer team by Barcelona in the Champions League final Wednesday, police told CNN.
The driver, whom police did not name, drove a minibus into a crowd celebrating the Spanish side's victory.
Ten people were injured in the incident in the town of Ogbo, where the driver was subsequently arrested, a Port Harcourt Police spokeswoman said.
"He was displaying his anger at his team losing the match. The driver had passed the crowd then made a U-turn and ran into them," spokeswoman Rita Inomey-Abbey said.
Both Manchester United and Barcelona have a large fan base across the African continent, with millions tuning in to watch European soccer.
Meanwhile, more than 100 people were arrested in a Barcelona city center in the early hours of Thursday morning after the Catalan team's 2-0 victory in Rome in the final of Europe's top soccer competition.
Police arrested 119 people after violence flared at a special celebration party in Place de Catalunya near the Las Ramblas thoroughfare. At least 238 people suffered minor injuries.
City officials estimated the damage at up to 100,000 euros ($140,000) as the youths attacked police with bottles and damaged shops, parks and public utilities such as lampposts.
The trouble took some of the gloss off the achievement of Barcelona, which became the first team to win the Champions League, Spanish League and Spanish Cup titles in one season.
Manager Josep Guardiola led the club to glory in his first season in charge, ending a period of three years without a trophy.
