@matt0177 And thank you for being my friend and taking over my baby sec587 and making it even better

[Dutch Osint Guy Nico @dutch_osintguy]

A professional milestone I’m genuinely proud of.

I’ve been promoted by SANS to Principal Instructor.

Teaching OSINT and intelligence analysis has always been a passion, but it’s the interaction with students (the questions, challenges and discussions) that makes it so rewarding.

Thank you to @SANSInstitute Institute for the recognition, opportunity and trust, and to every student who has been part of that journey.

Principal Instructor, but forever a student of the craft.

ICYMI #overasselt

[Dutch Osint Guy Nico @dutch_osintguy]

There was a horrific incident in the city of Overasselt (Netherlands) that hit the global news yesterday. It is a drugs cartel related case. I've created a Dossier on this that will track this case and update every 12 hours.

Context:
Over the past 48 hours, Overasselt has been shaken by a major, fatal shooting and a large police operation.

Early Tuesday morning, at around 04:00, police responded to a suspicious situation at a house on Ewijkseweg. When officers arrived, they were fired upon. A 51-year-old man from Wijchen was found critically injured and later died.

Two police officers were also shot. They were taken to hospital and are now out of life-threatening danger. Colleagues reportedly gave them emergency treatment while the scene was still unsafe.

The incident involved a large group of masked individuals, some apparently armed. Police are reviewing footage and investigating what happened, who fired the shots, and the role of each person involved.

At least 34 people have been arrested in and around Overasselt, including during operations near Nijmegen station and on the A73 and A76 motorways. Police have seized weapons, vehicles, and digital devices. Some reports indicate a possible additional arrest overnight, but the official count remains 34.

The suspects include people from the Netherlands, Belgium, France, and Algeria. They are being questioned individually, and authorities have not yet announced charges or established responsibility.

Police and prosecutors describe the background as a possible long-running conflict. The property involved had also been targeted in a shooting last year. Media reports have speculated about an organised-crime or drug-conflict connection, but this has not been officially confirmed.

The stay-indoors advisory for Overasselt and nearby Nederasselt has been lifted. Police say there is no indication that suspects are still hiding locally, though the investigation and extra patrols remain ongoing.

The Netherlands #overasselt case is getting more serious by the minute. @Crimesite obtained some new footage with some serious threats.

What happened ? : Around , police received a report of a suspicious situation at a home on Ewijkseweg, where a large group of masked people had reportedly been seen.

When the first officers arrived, they were immediately fired upon. A critically injured 51-year-old man from Wijchen was found and later died. Two officers were shot and taken to hospital.

Police launched a major operation, including specialist arrest teams. Searches and arrests took place in Overasselt and surrounding areas, including near the A73, A76 and Nijmegen. Warning shots were fired during some actions.

By the end of the day, police had arrested 34 suspects. The two injured officers are out of immediate danger. The investigation is ongoing; police have not confirmed a motive or individual roles, so claims of a specific criminal connection remain unverified.

Contextl: the same Ewijkseweg address was reportedly targeted in a separate shooting in June 2025, but authorities have not publicly confirmed a connection to this week’s incident.
