Police are to send football fans text messages urging them to avoid violent behaviour in an attempt to halt the rise in domestic incidents associated with major play-offs.
Around 17,000 supporters at Sunday's Hibs Hearts derby will receive the message via bluetooth as they leave Easter Road asking them not to be violent to their partners when they get home.
The initiative is the latest in a series of measures to protect vulnerable people at a time when violence in the home spirals.
Police said the amount domestic abuse increases during the festive season and around derby matches.
An extra 750 police officers have been drafted in for Sunday's Celtic versus Rangers match at Celtic Park, and Strathclyde Police have contacted around 800 repeat offenders in the run-up to the game.
Officers will carry out bail and curfew checks, monitor pubs and patrol areas renowned for violence, and will also be advising potential victims on how they can protect themselves.
Superintendent Bob Hamilton from Strathclyde Police said: "Domestic abuse round about January the first is almost three times what it is on a normal day.
"That fact added to there being an Old Firm match thrown into the mix on January the third is something that causes significant concern.
"We're trying to put what we can in place to stop people becoming victims.
"It's a difficult challenge but we need to say to these people: it's not acceptable.
"These people take alcohol, walk from the pub and then assault their partners, and that's not acceptable.
"I'm not going to sit here and wait for someone to become a victim of a serious crime."
Chief Superintendent Gill Imery of Lothian and Borders Police added: "Unfortunately during the festive period, incidents of domestic abuse are known to increase.
"As a result, Lothian and Borders Police are actively trying to raise awareness of this issue and of organisations which can provide support, advice and assistance."
Hibs and Hearts players will wear white ribbon badges at Easter Road to support the White Ribbon Campaign against domestic abuse.
Hibernian manager John Hughes said: "We hope that by wearing white ribbons during the derby match our players will help highlight this important issue to a wide audience."
Hearts captain Michael Stewart said: "The Hearts' players are pleased to support this very important campaign during such a high-profile game against our city rivals."
