A couple who were arrested after making complaints about their daughter's primary school, which included comments made on WhatsApp, say police have paid them £20,000 in damages.
Rosalind Levine and Maxie Allen told the Times in March they were held for 11 hours on suspicion of harassment, malicious communications and causing a nuisance on school property.
Hertfordshire Police previously said the arrests "were necessary to fully investigate the allegations".
Ms Levine, from Borehamwood, told the BBC police had accepted liability for unlawful arrest and paid damages of £20,000, plus costs. BBC News has asked Hertfordshire Police to comment.
Ms Levine added she was "very pleased" with the outcome.
