How to Preserve Evidence Before Reporting Online Abuse

By Safe Child Guide Editorial Team

When a child has been bullied, threatened, groomed, or scammed online, evidence is the difference between a report that gets acted on and one that disappears. Platforms move accounts and content constantly. Messages can be deleted by the sender. Disappearing-content apps such as Snapchat can erase chats within minutes. The few minutes you spend preserving evidence before doing anything else are some of the most important in the whole response. Start with screenshots. On iPhone, press the side button and volume up button at the same time. On Android, press the power and volume down buttons together, or use the gesture set in your phone's settings. On Windows, the Snipping Tool or Windows key plus Shift plus S captures any area of the screen. On Mac, Command Shift 4 lets you draw a box around the area to capture. Screenshots save automatically to the Photos app or to a folder on your computer. Capture more than just the worst message. Investigators and platforms work from context. A single line out of context can be ambiguous; the same line within a conversation showing pressure, grooming language, or repeated contact tells a very different story. Screenshot the conversation in segments so the timeline is clear, and include any earlier messages that established the relationship, however innocent they look. Make sure each screenshot shows the username or handle of the other person, the date and time, and the platform's name or logo. Where the platform allows, screenshot the profile page of the account as well: bio, follower numbers, profile picture, and any other public information. Account details often change quickly once a report is filed, and the profile data you capture now may be unavailable later. For disappearing-content apps such as Snapchat, treat screen recording as the default rather than screenshots. Single screenshots may notify the sender, but they also only capture a single image. A short screen recording of you scrolling slowly through the conversation captures more context. On iPhone, add Screen Recording to Control Centre under Settings, Control Centre. On Android, Screen Recorder is in the Quick Settings panel on most devices. Save the evidence in at least two places. Keep the originals on your device, but also back them up to a cloud service — iCloud, Google Drive, OneDrive, or a private email to yourself. Add a brief note alongside the files: the date the incident happened, where the message arrived, your child's age, and a one-line description. If you ever go to police or court, this note becomes a contemporaneous record that helps establish the timeline. Do not delete the original messages from your child's device until reporting is complete. Many platforms ask for the message ID, URL, or thread to investigate effectively. If the messages cause your child ongoing distress, archive or hide the chat rather than deleting it, and consider switching off notifications for the relevant account until things are resolved. When reporting, attach the screenshots in the format the recipient expects. The Designated Safeguarding Lead at school usually wants images attached to an email. CEOP at ceop.police.uk has a form that lets you upload supporting files. Action Fraud takes evidence for online scams and financial crimes against children. The Information Commissioner's Office can handle data protection complaints, for instance where a third party has shared information about your child without consent. Each report is taken more seriously when supported by clear, dated, contextual evidence. Finally, protect your child from re-traumatising material. Once evidence is preserved, you do not need to keep looking at it. Move the folder somewhere that is not part of your daily phone usage, name it neutrally, and only revisit it when a report or investigation requires it. Evidence exists to help your child be heard — it should not become a wound you both keep reopening.
