Cell Site Analysis Supports Armed Robbery Gang Prosecution

Cell site analysis plays a vital role in supporting serious crime investigations, providing location-based evidence to establish the movements of suspects. IntaForensics’ expert cell site team was instructed to assist in a high-profile case involving a gang responsible for a series of violent armed robberies, burglaries, and vehicle thefts across the West Midlands and Staffordshire. 

Over a 7-month period, a group of offenders carried out a wave of armed robberies at pubs, supermarkets, and off-licences. Victims were threatened with weapons including machetes and axes, and vehicles stolen from earlier burglaries were used to facilitate further offences. The pattern of offending spread across multiple towns, causing significant distress in the affected communities. 

Following key arrests, a major investigation was launched by the police, incorporating extensive CCTV review, forensic examinations, and digital analysis. 

With over a dozen armed robberies committed across multiple towns and involving a coordinated group of individuals, the investigation required a methodical approach to establish the presence and movement of each suspect. The police had seized multiple mobile devices, but without clear attribution or contextual analysis, the raw call data alone could not conclusively link the individuals to the scenes of the crimes. 

The offences took place in various locations across the West Midlands and Staffordshire, often during late-night hours or just before business closing times. Investigators faced the challenge of connecting suspects to specific locations during specific time windows without relying solely on CCTV or forensic trace evidence. 

The volume of data was also significant. With months of activity to review, including thousands of call records, texts, and cell site connections, the case demanded expert-level analysis to extract meaningful patterns. It was essential not only to assess the presence of devices at key locations but also to interpret the mobile network behaviour in relation to the timing, geography, and logistics of each offence. 

The IntaForensics Cell Site Analysis experts were instructed to review the relevant phone data and provide independent analysis and testimony. The work involved:

Cell Site Mapping and Attribution
Analysis of Call Data Records (CDRs) and mobile network usage was required to map the activity of key handsets in the case. This included plotting connections to specific cell towers in proximity to crime scenes and vehicle theft locations.

Data Analysis and Pattern Recognition
Comparing device usage and cell site data connections against known offence times enabled experts to assess the possibility of each device being present during the criminal activity.

Physical Surveys and Travel Path Reconstruction
Surveys were conducted to verify if the mobile masts used by the devices could provide coverage at offence locations. Experts were able to establish potential movements of device in the lead-up to and aftermath of each robbery or burglary, by analysing the call data records.

Expert Witness Testimony
One of our cell site experts provided court-admissible reports and gave expert evidence at Crown Court. This testimony helped to present the technical findings in a straightforward manner, enabling the jury to understand the mobile evidence and how it related to the broader investigation.

The cell site evidence provided by IntaForensics played a pivotal role in supporting the prosecution case. By analysing mobile phone call data records, our experts were able to demonstrate potential presence and movement patterns of several devices during key offences, including armed robberies and vehicle thefts across multiple locations. 

This digital evidence was used to show how individual devices moved in a coordinated manner before, during and after specific incidents. This supported the theory of a planned and organised crime group. When reviewed alongside CCTV footage, forensic findings and witness statements, the location data provided an additional layer of independent corroboration that strengthened the timeline and association between the devices and the crimes. 

The combination of this evidence helped secure the conviction of 6 individuals, who were sentenced to a combined total of nearly 60 years in prison.
