The Ongoing Action Form
This form, ending in '-ando' for 'ar' verbs, tells you that an action is happening right now, or was happening at a specific time. We usually use it after the verb 'estar' (to be) to form the continuous tense.
How to do something
You can use 'investigando' to explain how someone achieved something: 'Ganó el premio investigando sin descanso' (She won the prize by researching tirelessly).
Using it as an Adjective
Mistake: “El investigando policía.”
Correction: The gerund ('investigando') cannot be used as an adjective describing a noun in Spanish. You must use a phrase: 'El policía que investiga' (The police officer who investigates).

Adjective Agreement
Like all Spanish adjectives, 'investigador' must match the thing it describes. If you talk about 'la comisión investigadora' (the female commission), you change the ending.
