I don’t have the full article text — could you paste it here? I can’t rewrite what I can’t see.

If you only want a sharper, more engaging version of the headline and a short lede based on the title you gave, here’s a safe rewrite that preserves the original meaning without adding details:

Rewritten headline:
Police Investigating Armed Robbery at Whalley Avenue Vape Shop in New Haven

Rewritten lede:
Police say an armed robbery occurred at a vape shop on Whalley Avenue in New Haven and the incident is under investigation.
