Police in Northern California say they are responding to an incident involving an “active shooter” at YouTube headquarters.

Gunshots were reported at the company’s campus in San Bruno, south of San Francisco. Ambulances are at the scene and authorities have warned the public to stay out of the area.
Google, which owns YouTube, has said it is investigating a possible “gunfire incident”.
Unconfirmed reports from local media say the shooter is a woman.

Gay dating app Grindr has defended itself after an outcry over how it shared data with two external companies.

On Monday it emerged the app had, among other things, provided information on HIV status, including date last tested.
Grindr said the data was shared in line with standard industry practices, and that it felt the app had been unfairly singled out.

Snapchat has launched a feature that enables up to 16 people to take part in a live chat together, using either video or just their voices.

The app’s members can also start tagging each other by username, using the @ symbol in their posts.
The changes will roll out over the coming weeks, the firm said.
