During an argument Thursday, the boy punched one of the brothers, while his great-grandmother and sister tried to separate them.
The boy then allegedly pulled out a handgun and pointed it at the group, threatening to shoot everyone involved, according to the report.
The women brought police a screenshot of a Twitter message from the 15-year-old boy, which included a picture of a bullet hole in an object and the caption “dis wat my gun do,” according to a Sandusky police report.
The message had since been deleted.
The group has had ongoing problems, and the boy and his girlfriend often post threats against the sister on social media, the women told police.
Police searched for the boy Friday at Compass Academy, but the school’s resource officer told them he didn’t attend class today.
They arrested him at his home in the 300 block of E. Market St. and charged him with two counts of felonious assault.
They transported him to the Erie County Detention Home.
The arrested boy’s mother came to the Sandusky Police Department later Friday and told police her son didn’t have a gun, despite the evidence on Twitter, according to the report. The other teens were “making it up to get him in trouble,” she said.
The brothers he allegedly threatened to shoot “jumped him” Thursday on his way to the school bus, and their sister punched him in the face three times, the mother said. She showed police a screenshot of a Facebook post from one of the brothers that day, which said he wanted to fight her son, because he could “use the work”
