The boyfriend of a woman killed in a horror crash alongside three children on a rural New South Wales road has been arrested.
Tania Murphy along with two of her sons and her nephew – aged between 10 and 12 – were travelling along a remote road when their car hit a pole, flipped and landed upside down in a farming canal in Yanco near Leeton, about 550km inland of Sydney, late last night.
The 36-year-old and the three boys were killed in the crash.

Murphy's boyfriend Dean Ingram, 32, is one of the people being questioned by police.
Police are investigating whether the pair were arguing moments before Murphy and the three children drove off.
The other person in custody is a 50-year-old woman.
The horror crash has left the Leeton community devastated.
Family members told 9News: "We're devastated, we simply can't believe they're all gone".
The family said they were in shock and what had happened still had not hit them.

Leeton Shire Mayor Tony Reneker said a feeling of "disbelief, shock and despair" is resonating throughout the town.
"It is such a tragedy to lose four people in a single-vehicle accident especially when three children are involved," he said.
"It is a ripple effect to the whole community."
Acting Assistant Police Commissioner Tracy Chapman said it was a tragic accident.
"A mother and three children have been involved in a motor vehicle collision. Our thoughts go out to their family, friends and community," she said.

The fatal crash comes as police warn drivers against driving while fatigued or under the influence over the Easter weekend.
"The message is simple: drive to the speed limit, focus on the road, not your phone, and make sure you have a plan B if you are drinking," Chapman said.
"For the last two years, we've seen seven fatalities on the road each Easter long weekend.
"The goal this year is to reduce that number."
The crash takes the road toll in NSW this year to 83.
