A corruption case involving a Taiwanese lawmaker's office has widened into a suspected Chinese spy investigation, dragging in the brother of one of Taiwan's most famous bakers — bad news for the politician, and awkward for a beloved food brand.

• Prosecutors say people tied to independent lawmaker Kao Chin Su-mei's office took money from China and built a network inside Taiwan.
• The office director and an assistant were detained and cut off from outside contact after a key suspect smashed his ankle monitor and fled.
• The detained director is the older brother of Chen Yao-hsun, the baker known for Taiwan's most sought-after egg yolk pastries.
• Chen posted about moving his shop into a department store, saying overnight queues were disturbing neighbors — and added that he does not need to explain everything.

Outlook: Prosecutors are widening the probe, so more arrests are likely, and Chen's brand will keep facing questions it says it will not answer.
