(TMZ): Bobbi Kristina's boyfriend Nick Gordon was arrested for driving like a maniac last night ... hours after Whitney Houston's daughter totaled a Chevy Camaro in a frightening wreck of her own.
Law enforcement sources tell TMZ ... Nick was taken into custody in Alpharetta, Georgia last night ... after cops say he was going 82 in a 35 on Northpoint Parkway .. a retail area with high pedestrian foot traffic.
One law enforcement source tells us, "We are fortunate because that's such a busy corridor with high end retail shopping retaurants and pedestrains at crosswalks."
The source adds, "At that speed, it's absolutely reckless."
We broke the story ... BK wrecked a Camaro in Alpharetta yesterday after losing control and careening down an embankment ... striking several trees along the way. Miraculously, she emerged from the accident unscathed ... but cops issued her a citation for failing to stay in her lane.
Attempts to reach Nick for comment were unsuccessful.
