Baton Rouge police have arrested a 20-year-old man in the Friday shooting death of LSU basketball player Wayde Sims.

Police announced at a Saturday news conference that they had arrested Dyteon Simpson of Baker, Louisiana, and charged him with second-degree murder. He was booked into East Baton Rouge Parish Prison, and bond was set at $350,000.

According to Baton Rouge Police Chief Murphy Paul, Simpson allegedly shot Sims after Sims joined a fight to defend one of his friends. District attorney for the Parish of East Baton Rouge Hillar Moore said the case would proceed to a grand jury.

Sims, 20, died of a gunshot wound at a local hospital. The shooting took place near Southern University, north of downtown. Sims was a junior forward and a native of Baton Rouge. He averaged 5.6 points and 2.9 rebounds in 10 starts for LSU last season. He was the Louisiana Gatorade Player of the Year after his junior season at University High School, and his father also played at LSU.

In a statement released after the news conference, LSU athletic director Joe Alleva thanked authorities for their work and said the "entire LSU family continues to mourn the loss of Wayde Sims."
