Four young men in costumes calmly walked into a Pantego house and robbed 30 to 35 teens at a Halloween party Saturday night, Pantego police said Tuesday.
Two of the robbers were armed with handguns and ordered everyone to the floor as they collected money, jewelry and cellphones, police said.
A father who showed up to pick up one of the partygoers was seriously injured after he confronted one of the robbers, police said.
No one had been arrested as of Tuesday.
Never miss a local story.
The home invasion happened about 11:15 p.m. Saturday in the 1700 block of Robin Drive in Pantego.
"They wore bandannas when they came to the door," Pantego Police Chief Joel McKinney said. "The kids who answered the door thought they were just there for the party, so they let them in."
The costume party was for students mostly from Arlington High School, with two adults present, McKinney said.
The four robbers walked around the party until a student confronted them.
"The girl whose home the party was at wanted to know who they were," McKinney said. "That's when they brandished the weapons and ordered the students to the floor."
They then started collecting items from the students, police said.
At some point, the father of one student came to the front door.
"One of the suspects opened the door and that father figured out what was happening," McKinney said. "The father then got into a fight with the suspect."
The fight spilled out into a yard, where a second robber joined in.
The two beat the man up and then, joined by the other two robbers, stole a car and drove away. Authorities discovered the car in Fort Worth a few hours later.
After police arrived, the father, who was not identified, was treated at a hospital and released.
No one else was injured.
