The Unidad de Delitos Tecnológicos (Technological Crimes Unit) is a specialized division of the Spanish National Police and Guardia Civil dedicated to investigating crimes that involve digital technology, cybercrime, and electronic evidence — including those that affect minors, sexual offences, and online exploitation.

Let’s break it down clearly and in-depth so you understand who they are, what they do, and how they may be involved in a case related to underage sexual abuse or mobile phone data.

🧠 WHAT IS THE UNIDAD DE DELITOS TECNOLÓGICOS?

The Unidad de Delitos Tecnológicos is a cybercrime unit that works to detect, investigate, and dismantle crimesinvolving:

Computers
Mobile phones
Internet platforms
Social media
Online communications
Encrypted or hidden digital content

They act as the digital detectives of Spain’s police forces.

There are two main arms:

Brigada de Investigación Tecnológica (BIT)
- Part of the Policía Nacional (National Police)
- Focused on urban areas and national/international crimes
Grupo de Delitos Telemáticos (GDT)
- Part of the Guardia Civil
- Active in more rural or suburban zones

🕵️‍♀️ WHAT DOES THIS UNIT DO?

These cybercrime units investigate cases such as:

🔞 Crimes Against Minors

Grooming online (acoso sexual de menores)
Sextortion or blackmail involving explicit images
Sharing of child sexual abuse material (CSAM)

📱 WHEN WOULD THEY HANDLE A CASE?

These specialized units are usually brought in when:

The crime involves digital communication (texting, sexting, blackmail)
There is evidence stored in a phone, tablet, or computer
The suspect used encrypted apps or attempted to delete content
There are multiple victims, such as in cases of child pornography rings
Online platforms (like WhatsApp, Instagram, Facebook) are part of the abuse

If you report underage sexual abuse and say something happened through a phone or online, the police will automatically escalate the digital part of the case to these specialists.

🧪 HOW DO THEY HANDLE MOBILE PHONES?

The phone is seized by police or handed in voluntarily
It’s transferred to the Unidad de Delitos Tecnológicos
A forensic copy is made (to preserve the original evidence)
They use specialized tools like:
- Cellebrite
- XRY
- Oxygen Forensic Suite
They extract and analyze:
- Chats (e.g., WhatsApp, Signal, Snapchat)
- Photos and videos
- Browser history and app usage
- GPS/location data
- Deleted content if possible
They produce a forensic report (Informe Pericial) with:
- Screenshots, chat transcripts
- File timestamps
- Device logs to confirm or refute allegations

⚖️ COLLABORATION WITH COURTS

The unit works under judicial order — they cannot access phones without a judge’s permission unless it’s an emergency (e.g., imminent harm to a child).
Their reports are sent directly to the judge or Fiscalía de Menores (Juvenile Prosecutor).
Their agents may testify in court as expert witnesses.

👧 SPECIAL PROTECTIONS FOR MINORS

If the victim is underage, they follow strict protocols:

They do not expose the child to explicit content unless absolutely necessary
Any child sexual images found are handled with special permission and stored securely — not shown in court unless required
They work closely with psychologists and child protection units to ensure the investigation is trauma-informed
