Remember Joshua Walter, the teen fashion model from Queens who made headlines last fall after his 37-year-old lover, a former teacher, sued the city for firing her over their affair? He's back in the news, and if you recall the way he dealt with tabloid reporters outside his house in November— "You want to see assault? Turn that thing off!"—you won't be too surprised by the latest turn of events. Walter, now 20 and a dad, was arrested late Wednesday night with three others and charged with robbing 15 gas stations and delis in Queens and Greenpoint. According to the Post, they all confessed. The spree began June 14th and ended on Sunday at a Dunkin' Donuts on Horace Harding Expressway, where Walter allegedly pistol-whipped one of the victims. Police spotted the crew around 1:30 a.m. Thursday in a maroon Chevy Astro van matching the description of the getaway car; after being pulled over the young men ran but were quickly apprehended, and a .380-caliber automatic handgun was found in the van. Approached by the Daily News outside her Queens home, Walter's poor mother shouted, "I got something to say: Leave my family alone!"
