A 33-year-old woman who tried to poison her estranged husband with antifreeze has been charged with attempted murder.

Kristen Hogan from Ridgefield, Connecticut, was arrested on Friday and accused of putting antifreeze into a bottle of wine and iced tea at her husband's home.

The pair have been locked in a bitter custody battle relating to their child.

On August 10, her 34-year-old husband drank a small amount of spiked wine and kept waking up sick in the middle of the night.

The next day he began to vomit, according to documents released by the Connecticut state police.
