PANAJI: A crumpled note, written with eyeliner, recovered from a bag belonging to Suchana Seth indicates that she was upset over the custody of her four-year-old son, whom she allegedly put to death, a Goa police official said on Friday.

Seth (39) was arrested on Monday night for killing her son in a service apartment at Candolim in North Goa. She and her husband are estranged and their divorce proceedings are currently underway.

A senior police official said that a crumpled note, scribbled with eyeliner on a tissue paper, was found in her bag. "We would not like to disclose the content of the note but it indicates that she was upset over the custody of her child," he said.

The note was not found in the bag where she had stuffed her son's body after killing him, he said.

Police said that a court had granted visitation rights to her husband Venkat Raman which had not gone down well with the accused.

Seth was arrested in Chitradurga district of Karnataka while trying to reach Bengaluru in a taxi.
