Police said seven people were shot after a fight broke out at a house party in east Houston early Saturday morning. The incident occurred around 1:45 a.m. at an "instant house party" that formed after it was promoted on Snapchat.

"It was just a random group of people receiving an invite (on the app)," said Detective Sean Ragsdale, CBS Houston affiliate KHOU reports.

Ragsdale said there were between 30-50 people at the party, including teens and adults.
