Crimestoppers has received a record number of reports about domestic abuse, drug dealing, child harm and neglect during lockdown.
Compared to previous months, reports about those at risk of domestic abuse increased by 81% and doorstep crime calls increased by 30%.
Drug-dealing complaints increased by 40% and visits to the Crimestoppers’ website trebled in April.
The charity also heard from concerned friends and neighbours about children at risk.
One anonymous report highlighted a child being neglected and constantly crying in pain.
Drug dealers continued to operate despite lockdown measures, Crimestoppers said.
Angela Parker, national manager for Crimestoppers Scotland, said: “The past few months have been very challenging for people across Scotland.
“As a charity, we needed to raise awareness of the risks and harm the most vulnerable in communities would experience during lockdown.
“Often people know or suspect who’s responsible but for whatever reason, don’t want to speak to the police or get involved.
“We are so encouraged and grateful for the people who trusted our 100% anonymous guarantee and told us about those at risk.”
Police Scotland assistant chief constable Gary Ritchie said: “Crimestoppers is an integral partner in helping us offer a tangible and secure alternative for those who wish to remain anonymous in reporting crime and concern for others.
“We recognise how challenging recent times have been for people and I would like to take this opportunity to thank communities across Scotland for the crucial role they are playing in the collective effort to stay safe, protect others and save lives.”
