A St. Peter man has been arrested in connection to an assault in Mankato over the weekend.
Police arrested 21-year-old Trevor Shelley around 6:15 p.m. Monday at his home in St. Peter. Police said witnesses of the assault had come forward, giving them enough information to make the arrest. He is expected to be arraigned in court Wednesday.
Police in Mankato had asked for the public's help to help identify the second suspect in the attack. During a news conference Monday, police showed footage from city security cameras in the entertainment district of Mankato that showed a white male, who police determined to be Shelley, in his early 20s wearing a red shirt running from the scene.
Isaac Kolstad remained in critical condition at Mayo Clinic Health System in Mankato Tuesday after he was punched and kicked during a fight. Doctors have said they do not know if the 24-year-old will live after suffering brain bleeding and skull fractures.
He had surgery Tuesday morning, which went well, his family said.
Philip Nelson, a former University of Minnesota quarterback, has been accused of kicking Kolstad in the head after another suspect knocked Kolstad out during a brawl after bar close in Mankato early Sunday morning.
Nelson, 20, was arrested Sunday morning and is facing two felony assault charges. He is currently out on $20,000 bail. Shelley is expected to face the same charges.
Nelson transferred to Rutgers University this winter to play football. Coach Kyle Flood announced Tuesday Nelson has been dismissed from the team.
The case remains under investigation.
