"Right after, we found out [about the stabbing] from the hospital because they recognised the kit and spoke to the club. They said: 'We have a player from your team here called Mirsha. It's all we know because he has nothing on him.'"
Left-back Herrera Gastelum had spent five years with the club, having joined them when he was 15.
He had already trained with the first team on several occasions while Diego Maradona was manager.
Herrera Gastelum has a brother, who plays for Xolos de Tijuana's under-17 side.
